A wide range of sensitive industrial processes and consumer products require high-purity and ultra-pure water.  They range from boiler and turbine corrosion control in electronic power generation to the production of sophisticated semiconductors and microelectronics to life-saving pharmaceuticals and everyday foods and beverages.

ECD’s new Model NA6 Sodium Analyzer features an advanced glass electrode sensor that measures sodium in water to the parts per billion (ppb), parts per million (ppm) or milligram per liter (mg/l) levels.  The sodium sensor’s measurement range of 0.1 to 10 ppb is based on the proven accuracy of ECD’s proven sodium glass electrode sensor for the online potentiometric detection of low ppb traces of sodium.

This ECD sodium glass electrode sensor when exposed to raw process or treated process water produces an electronic signal potential proportional to the log of the sodium concentration. The sample is exposed to a reagent vapor, which raises the sample pH to 11 to eliminate any pH or ammonium interferences that would affect measurement accuracy.  Highly reliable too, reproducibility is ±0.2 ppb or 5%, whichever is greater at constant temperature.

To ensure dependability and safety, the NA6 Analyzer features a dual compartment design.  The wet sample, sensor and reagent are all completely separated in one compartment of the analyzer from the electronics and user-interface display located in the second compartment.  The electronics are always dry and safe from moisture for superior reliability.

For maximum user flexibility by plant technicians, the NA6 features a dual-function design. When in continuous operation, it features a T90 180 sec (0 to 10 ppb) delay time. Its “grab sample” capability also enables the unattended analysis of manually collected samples. The results of external samples are stored in the analyzer’s data logger, which includes time and date stamping information for history logging.   

Ready to go right out of the box, the ECD NA6 Analyzer is easy to install by a single technician in less than 30 minutes with no special training or tools. All that needs to be done is connect the power, the sample line and the reagent lines.   The analyzer is then fully operational.

The NA6 analyzer offers a choice of a manual 1-2 point calibration mode or a 2-point automatic calibration mode. The 2-point automated calibration mode minimizes operator intervention and ensures the most accurate results are obtained.  Free selectable calibration intervals are available too. The results of the last ten calibrations are stored in the analyzer’s internal data logger.

The NA6 Analyzer includes a color touchscreen user interface with multi-lingual capability. It displays measured values and status information in a large easy-to-read format. The design is highly intuitive with full access to menus and functions.  The built-in data logger comes with USB download capability.

Two 4-20 mA data outputs are provided with the NA6 Analyzer, which are compatible with Modbus RTU485 plant control system communications.  Three onboard SPDT relays are programmable to set alarms. The standard power supply is 120/240 VAC, 50/.60 Hz, with an available 24 VDC optional configuration.

The rugged, long-life NA6 Analyzer operates over a wide temperature range from 41 – 122 °F (5 to 50 °C). Ingress protection is IP54 compliant.  For outdoor use, an optional cabinet enclosure is available for harsh weather conditions.

Simple to maintain, the NA6 Analyzer helps reduces plant measurement operating costs.  It features a low-reagent consumption design that minimizes consumables expenses.  There are no-moving parts to break or replace, ensuring a low life-cycle cost as well.

New IoT Web-Enabled CA900 Titration Analyzer Measures Alkalinity Automatically and Accurately

Ideal for Water & Wastewater, Food/Beverage, Pharmaceutical, Semiconductor

 

Anaheim, CA—January 26, 2018—Engineers and laboratory technicians responsible for maintaining alkaline and pH levels in balance to support a wide range of municipal and industrial water-based processes will find the new IoT web-enabled CA900 Titration Analyzer from Electro-Chemical Devices (ECD) automates the process of routine alkalinity measurement with a simple, accurate and cost-effective approach.

Maintaining water quality with the proper balance of pH and alkalinity levels is essential in many different processes—everything from drinking water to wastewater processes, as well as in irrigation water, water-based beverages and pharmaceuticals, electronics manufacturing and more.  Alkalinity is a measure of the capacity of water to neutralize acids and affects pH levels in water.  It occurs naturally in groundwater and its levels are influenced by rocks and soils, salts, certain plant activities and in some cases by industrial wastewater discharges.

ECD’sadvanced CA900 Titration Analyzer for alkalinity measurement is so easy to install and start up that a technician can do it in less than 15 minutes.All that is necessary is to perform simple connections of the sample,waste and reagent lines and then power up the factory pre-calibrated analyzer.Wall mounting hardware comes standard with each analyzer, but an optional bench top stand with reagent holder also is available.

Four different ECD factory pre-set alkalinity calibration ranges are available for the CA900 Titration Analyzer: 0 to 50ppm, 50 to 200 ppm, 200-1000 ppm, a 0 to>1000ppm. Users simply order the desired calibration range, and the analyzer comes ready to go right out of the box.The analyzer’s full-featured design also comeswithfour4-20analogoutputs, an Ethernetdigitaloutputand four user-configurable alarm relays.

Accessing information or customizing analysis routines are both easily accomplished.

 

ECD’s CA900 Titration Analyzer for Alkalinity                                                         

 

With the CA900 Titration Analyzer’suser-friendly menu structure and touchscreen interface.The analyzer also can be web-enabled as a powerful internet of things (IoT) tool for remote monitoring and interfacing with personal handheld devices such as controllers, mobile phones, tablets, laptops, and computers.

To determine and maintain water quality, accurately measuring the alkalinity of the water is critical to assess its relationship and impact on pH levels. Titration analysis with the CA900 Analyzer calculates alkalinity by dispensing known doses of a titrant fluid into a reaction cell while monitoring the pH level to its end point.  The analyzer then uses the titrant concentration and amount dispensed to calculate the level of alkalinity measurement.

The CA900 Titration Analyzer typically performs a single alkalinity measurement per analysis cycle.  Its standard program sequence consists of a cleaning cycle, sample acquisition, monitoring of pH, the addition of the titrant fluid, mixing the fluid, calculation of results and data storage.  The desired frequency of analysis between cycles can be easily modified to the requirements of the user’s process.

The versatile CA900 Titration analyzer is designed with up to four different sample lines that can be connected to the analyzer.  Numerous analysis configurations can be easily set up and programmed depending on the specific process control application and/or environmental or other compliance requirements.

Measuring alkalinity levels with ECD’s CA900 Titration Analyzer is especially important for the effective treatment of both municipal drinking water and wastewater, where it can affect the wastewater anaerobic digestion process.Alkalinity in surface water generally results from the presence of calcium carbonate, CaCO3, which has been leached from rocks and soil and then enters surface or groundwater systems.

All-In-One High Range Free Chlorine Analyzer For Food Rinse, Wash and Disinfection Applications

Economical, Easy-To-Install Panel Mount System Offers Low Maintenance

 Anaheim, CA—March 20, 2017—Food processing engineers responsible for rinsing, washing and disinfecting fruits, vegetables and other disinfecting processes will find the new plug-n-play FC80 High Range Free Chlorine Analyzer from Electro-Chemical Devices (ECD) simplifies water-based disinfection while installing easily and requiring less maintenance for lower total cost-of-ownership.

The highly reliable FC80 High Range Free Chlorine Analyzer monitors free Chlorine in produce disinfection supply water, cleaning and disinfection of water supply lines, and cleaning solution water samples from 0.05 – 200 ppm Chlorine (Cl2). The FC80 is ideal for the monitoring Cl2 levels in disinfection processes to help ensure the elimination of disease-causing pathogens including E. coli, Cyclospora, Salmonella and Hepatitis.

High concentration Cl2 disinfection is utilized in a variety of food processing operations and produce packing lines.  All of these Cl2disinfection techniques, however, require the introduction of liquid or solid Cl2 into water tanks that are connected to washer or spray line systems.

According to the U.S. Food & Drug Administration (FDA), liquid chlorine and hypochlorites are generally used in the 50 to 200 ppm concentration range with a contact time of 1 to 2 minutes to sanitize produce surfaces and processing equipment. Hypochlorous acid (HOCl) is the form of freely available chlorine that has the highest bactericidal activity against a broad range of microorganisms.

The FDA states that in water-based solutions, that the equilibrium between hypochlorous acid (HOCl) and the hypochlorite ion (OCl¯) is pH dependent with the concentration of HOCl increasing as pH decreases. HOCl concentration is also significantly affected by temperature, presence of organic matter, light, air, and metals.  

The plug-n-play FC80 High Range Free Chlorine Analyzer installs quickly right out of the box.  The FC80’s advanced panel mount design includes built-in flow control, which eliminates the need for complicated pressure regulators and rotometers.  Built-in automatic pH compensation also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs.

            The FC80’s panel mount design incorporates a constant head flow control device, a pH sensor, a Cl2 sensor and ECD’s T80 analyzer/transmitter conveniently mounted on a PVC panel. Connect the sample/drain lines, outputs and power and it is ready to use. Calibration and standardization is accomplished by DPD comparison.

Free Cl2 exists in solution as a pH dependent ratio of hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10). The ECD T80 free Cl2 sensor measures only the hypochlorous acid component of the free Cl2 and the analyzer calculates the balance using either the measured pH or a user defined fixed value. The use of the pH sensor provides accurate compensation for samples between pH 6 and pH 9 eliminating the need for expensive sample conditioning systems.

The FC80 Analyzer is available with either 110-240 VAC or 24 VDC power.  Parameters can be graphically displayed with user defined line, bar or gauge style graphs. The standard configuration has two 4-20 mA outputs/MODBUS RTU, and three SPDT relays. User configurable as Hi/Lo alarms with expiration timers, periodic timers, or fault alarms.

The user friendly FC80 is available with an optional Auto-Clean feature that includes a solenoid actuated spray cleaner using either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle.

Dual Range HP80 Hydrogen Peroxide Analyzer Suitable for Disinfection or Bleaching Processes

Ideal for Municipal Water Treatment, Pulp/Paper, Food/Beverage,

Petrochemical Refining, Power Generation and More

 

Irvine, CA—April 27, 2016—With a versatile dual parameter measurement range capability, the advanced HP80 Hydrogen Peroxide Analyzer from Electro-Chemical Devices (ECD) is a highly flexible and reliable instrument designed to measure H2O2 in both the parts per million (ppm) range and the percent solution range to support a variety of process applications.

Process and plant engineers will find the HP80 Analyzer is an easy-to-use measurement solution that’s ready to go right out of the box with a plumb-and-play design, which a single technician can set up in less than 15 minutes with no special tools.  It’s a complete analyzer system including an H2O2 sensor, a pH sensor, a constant head flow control device and transmitter with power supply all mounted on a PVC wall panel that’s ready to hang.

H2O2 is a colorless liquid that in high concentrations gives off an irritating acidic odor. It is a strong oxidizer, stronger than either chlorine or chlorine dioxide. Hydrogen peroxide reacts very fast. It will then disintegrate into oxygen gas and water without the formation of harmful byproducts and also increases the amount of oxygen in water.

H2O2 is used by municipalities as an oxidizer to remove metals from raw well water sources.  The pulp and paper industries extensively use H2O2 as a bleaching agent to give paper that crisp white look. Other uses include as a disinfectant in cooling towers and municipal wastewater treatment plants.

An effective bactericide, H2O2 does not form any harmful disinfection byproducts (DBP’s), as opposed to the typical chlorine products for drinking water and wastewater treatment that do. It decomposes naturally into oxygen and water and does not form a residual that has to be removed from the treated water before it is released to the environment.

The HP80 Analyzer features amperometric H2O2 sensors. These amperometric sensors are manufactured with a gold cathode, a silver anode and a rugged microporous membrane. The H2O2 sensors are smart sensors with their identity and calibration information stored internally. Communication between the T80 Transmitter and the H2O2 sensor is via MODBUS. The sensors are flow sensitive requiring a minimum flow rate of 0.5 ft/sec, above this flow rate, the reading is virtually independent of the flow rate.

   A constant head flow control device (CFD) maintains the optimum flow rate moving past the sensor for sampling purposes.  The CFD’s automatic flow control capability eliminates the need for pressure regulators and rotameters, which are required by many other H2O2 analyzers, to reduce system maintenance and lifecycle operating costs.  The minimum flow rate required by the CFD is 10 gal/hr, and the maximum flow rate is 80 gal/hr with the sample draining at atmospheric pressure.

The HP80’s H2O2 sensors feature a measurement range of 0 to 200 ppm (2000 ppm, 2%, 20% optional).  The pH sensor has a range of 2 to 11 pH.  Operating temperature range for these sensors is 0 to 45°C (32 to 113°F) with automatic temperature compensation for the H2O2 sensor.

An optional sensor auto clean configuration is available, which includes a solenoid actuated spray cleaner that provides either a 30 psi process water or air.  The spray cleaner removes films from the sensor head, which over time can affect measurement accuracy.  There is rarely a need for manual wiping of the sensor head by maintenance technicians with the spray clean configuration. The sensor’s maintenance requirement is typically to replace the electrolyte every six months and replace the membrane cap once a year.

Two-In One UV Analyzer Family for Disinfection Measures Ammonia, Nitrate Or COD In Water or Waste

Ideal for Muni Water and Wastewater, Food/Beverage, Pulp/Paper and More

 

Anaheim, CA—March 30, 2016—Water engineers responsible for municipal or industrial water and wastewater will find the new versatile single or dual parameter CA-6 UV Family of Spectroscopic Analyzers from Electro-Chemical Devices (ECD) can monitor any two selected parameters in separate measurement ranges for ammonia, nitrate or chemical oxygen demand (COD 254 nm).

ECD’s CA-6 UV Analyzer Family provides a highly accurate, reliable and economical on-line sampling system that’s designed with UV absorption sensor technology to monitor harmful pollutant parameter levels.  The CA-6 Analyzer’s sensors are available in multiple parameter measurement ranges: Ammonia from 0-10 mg/L or 0 to 1000 mg/L; Nitrate from 0-30 mg/L, 0-100 mg/L, or 0-250 mg/L and COD 254 nm from 0-200 mg/L or 0-20,000 mg/L.

Each model is easy to order with either a single parameter or dual parameters in the factory pre-calibrated measurement ranges.  Everything needed comes in one box ready to install and start-up.  A single technician can complete the installation process in 15 minutes by connecting the sample, waste and cleaning solution (reagent) lines and powering up the analyzer.  Accessing the chosen factory pre-calibrated parameter data or customizing an analysis routine is easily done with user-friendly intuitive menus and a touch screen display.

     Each parameter is analyzed based on the measurement of UV absorption in the sample.  The absorbance of the solution or gas is measured through a quartz flow cell at a specific wavelength using a long-life Xenon lamp and photo detectors.  The absorbance level is directly related to the sample concentration according to Beer-Lambert’s Law, which correlates the attenuation of light to the properties of the material through which the light is traveling.

To measure Ammonia, a reagent is added to the liquid sample and converts the ammonia to gas for measurement by the CA-6’s UV sensor with a fast Fourier transform algorithm that provides a measurement equivalent to the level of Ammonia.  A water temperature probe performs automatic temperature compensation for high accuracy.

In measuring the Nitrate found in turbid, organic rich wastewater, the CA-6 UV’s advanced self-cleaning design relies on the strong absorption of UV light by the chromophore N-O, which again is according to Beer-Lambert’s Law. Automatic internal linearization compensates for high concentrations of Nitrate.   A second wavelength and detector compensates for dirty matter in the flow cell to ensure high accuracy and reliability.

For the measurement of COD 254 nm, the CA-6’s sensor detects UV light absorption by unsaturated organic molecules at the 254 nm wavelength.  COD 254 nm levels in river water and municipal wastewater are closely correlated to the permanganate and dichromate water standard methods.  Measurement is extremely responsive, less than 10 seconds and requires no reagents or calibration solutions.

Accuracy is 5% for the measurement of Ammonia, Nitrate and COD with the CA-6 UV Analyzer based on a sample temperature range of 0 to 80°C, but the sample must be liquid and not frozen.  Repeatability varies based on the parameter chosen and the single or dual parameter configuration, ranging from 0.15 to 3 percent.

The versatile CA-6 Analyzer is designed with four alarm relays.  A single 4-20 mA analog output is included with 12-bit resolution.  RS232 communications are provided for data download to a CSV file, with an optional RS485 MODBUS communication module available.

Green Friendly PA80 Peracetic Acid Analyzer Helps Maintain Disinfection Without Harmful Byproducts

Ideal for Food/Beverage, Medical, Pharmaceutical and Muni Water Processes

 

Irvine, CA—February 17, 2016—Process and plant engineers responsible for maintaining sanitary product, process and equipment environments will find the new panel mounted      PA80 Peracetic Analyzer from Electro-Chemical Devices (ECD) simplifies process monitoring to ensure disinfection without the need for potentially harmful disinfection byproducts (DPBs).

The plumb-and-play design of ECD’s economical PA80 Peracetic Acid Analyzer allows a single technician to install the unit right out of the box with no special tools or complex calibration routines. Ready to go from the factory, the PA80’s cost-effective design includes built-in flow control, and so there’s no need to purchase or install pressure regulators and rotameters, which are typically an extra cost with many other types of liquid analyzers.

Peracetic acid is a colorless liquid with a characteristic pungent odor similar to vinegar.

PAA is produced by a reaction between hydrogen peroxide and acetic acid.  Produced typically as an equilibrium solution combining these agents, PAA is supplied in concentrations of 5 to 15 percent. It is a powerful oxidizer, stronger than either chlorine or chlorine dioxide.

The rugged and reliable ECD PA80 Peracetic Analyzer features multiple PAA measurement ranges:  0-20, 0-200 and 0-2000 ppm.  Providing multiple measurement ranges allows plant engineers to select the monitoring range that best fits the requirements of their product batch recipes, their processes and equipment cleaning requirements.

The food and beverage, medical and pharmaceutical industries all rely on PAA as a cleaner and sanitizer of process equipment, medical instruments and for bottle washing. It is also used as a disinfectant in municipal wastewater treatment and industrial cooling towers.

    PAA is a highly effective bactericide that does not form any harmful disinfection by products (DBP) like many chlorine products do. It decomposes naturally into acetic acid and water and does not form a residual that has to be removed from the treated water.

The PA80’s plumb and play design incorporates a constant head flow control device, a pH sensor, a peracetic acid sensor and ECD’s T80 analyzer/ transmitter—all conveniently mounted on a PVC panel.  Plant technicians simply connect the sample and drain lines, connect the power and outputs, and the PA80 is ready to use. Calibration is accomplished by a grab sample comparison.

The PA80 Analyzer’s transmitter is 110-240 VAC or 24 VDC powered and allows either parameter to be graphically displayed with user defined line, bar or gauge style graphs. The standard configuration has two 4-20 mA outputs, three alarm relays and an industry standard MODBUS RTU (remote terminal unit).

Relying on precision amperometric PAA sensors that are flow sensitive, the PA80 provides accurate measurement with a minimum flow rate past the sensor of 0.5 ft/sec;

above this flow rate the output is virtually flow independent. The PA80’s constant head flow control device (CFD) maintains the optimum flow past the sensor over a wide range of incoming sample flow rates. The minimum flow required for the CFD is 10 gal/hr, and the maximum flow rate is 80 gal/hr with the sample draining at atmospheric pressure.

To reduce maintenance technician time and costs, the PA80 features an optional auto clean configuration, which includes a solenoid actuated spray cleaner that uses either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle.  The optional spray cleaner also eliminates fouling to protect batch sensitive products and prevent process line downtime.

Efficient Colorimetric Analyzer Helps Monitor Troublesome Manganese & Iron In Drinking Water

Ideal for Muni Water, Food, Beverage, Textile,

Semiconductor & Other High Purity Water Processes

 

AA038726

Anaheim, CA—June 16, 2016—The easy-to-use and economical CA6 Colorimetric Analyzer from Electro-Chemical Devicesprovides accurate and reliable measurement of manganese (Mn) or iron levels in municipal drinking water production, food/beverage processing and other high purity water processes.

The Model CA6 Colorimetric Analyzer is an on-line sequential sampling analyzer. A sequence of sampling, analysis and results processing is performed and repeated using colorimetric methods. This technology relies on an LED light source and a heated colorimetric cell designed for measuring trace amounts of manganese, iron and other analytes in water.

Manganese and iron are natural occurring elements found in air, soil and water.  Manganese and iron are essential nutrients for humans and animals.  Adverse health effects can be caused by inadequate intake or over exposure.  Manganese deficiency in humans is thought to be rare because manganese is present in many common foods.

Both manganese and iron have a strong, unpleasant metallic taste in water.  Ground water sources with manganese and iron can appear clear initially, but turn black (manganese) and orange-brown (iron) when exposed to air. An advisory from the U.S. Environmental Protection Agency (EPA) recommends reducing manganese and iron concentrations to or below 0.05 mg/L and 0.03 mg/L, respectively, which are the EPA’s secondary maximum contaminant levels (SMCL’s).

The EPA’s manganese and iron SMCL’s are based on staining and taste considerations, but are not federally enforceable regulations and are intended as guidelines. There are multiple municipal water treatment options for the removal of Mn and iron from drinking water.

 

AA038726

They all, however, rely on accurate and dependable water quality analysis prior to and after treatment.  The CA6 Colorimetric Manganese Analyzer is available in three ranges:  0-100 ug/L, 0-1 mg/L and 0-5 mg/L and the CA6 Colorimetric Iron Analyzer also is available in three ranges: 0-0.1 mg/L, 0-1.0 mg/L and 0-5.0 mg/L.

The CA6 precision online sequential sampling analyzer is lightweight and easy to install. Weighing less than 40 pounds, it can be wall mounted or simply set on a bench using the optional bench top stand. After the sample, waste and reagent lines have been connected to the analyzer and provided with power, the CA6 will begin its preprogrammed analysis sequence.              The CA6 is available with up to 4 channels (optional) each from a separate sample point. A simple, user-friendly menu structure and touchscreen interface makes it easy to access information or customize analyses.

The CA6 utilizes photometric differential absorbance to analyze manganese, iron and over 20 other common parameters including: aluminum, silica, nitrogen, iron and sulfate. It operates at a wide temperature range of 5-50°C and  offers repeatability of ±2% on the absorbance value if the turbidity <80 NTU and drift of ±2% per month on the absorbance measurement.

The CA6 Analyzer’s easy-to-use touch-screen display shows the measured parameter, analyzer status, percent reagent volumes and the menu bar, which provides access to the run, display, program, service and help menus. It includes two alarm relay outputs and a 4-20 mA channel that connects with programmable logic controllers (PLC’s) or distributed control systems (DCS’s).

The rugged and reliable CA6 features two separate compartments to isolate liquids and electronics and is enclosed in an epoxy powder coated, cold rolled steel cabinet. The liquids enclosure houses all the components necessary for sampling and reagent flow, mixing and reaction stages (sampling pump, reagent micro-pumps and colorimetric reaction cell).

Inductive Conductivity Analyzer

Inductive Conductivity Sensors – Model S80 IC

S80 Inductive Conductivity Sensors

The measurement of electrolytic conductivity is used to determine the amount of dissolved ionized material in a solution. It is most commonly made by measuring the electrical conductivity between two metallic electrodes placed into the solution. Inductive Conductivity is a non-contacting conductivity measurement made between two toroidal magnetic coils located inside a sensor that are inductively coupled through the solution’s conductivity. Since the toroidal coils are located inside the sensor’s PVDF (polyvinylidene fluoride) body, the inductive sensors are ideal for applications where corrosion or coating of the metallic electrodes will occur.  Inductive sensors excel in the higher conductivity ranges and in applications where coating is a problem. The chemically resistant PVDF (KYNAR) body is excellent for corrosive environments. These sensors are ideal for measuring high conductivity solutions and % concentration measurements. The measurement range of the inductive sensor is from 50 µS to 1000 mS. The Model S80 Inductive Conductivity sensors have the same ¾” diameter body as the rest of the S80 sensors. A wide array of installation methods are available, insertion into a pipe with a compression fitting or a valve retractable design for entry and removal into a pipe without shutting off the flow. Immersion into tanks or channels with a stand pipe and various flow cells are also available.

S80 sensors are a family of digital sensors designed for use with ECD digital analyzers, the Model T80 and X80 transmitters. The S80 sensors convert the analog signals into a temperature compensated digital protocol that allows two way communications with the transmitter. The type of sensor, identity and serial number are stored in the sensor’s memory along with three calibration registers. When connected to an ECD digital analyzer the sensor’s identity and calibration information are uploaded to the analyzer which configures the displays and outputs to the values appropriate to the sensor’s measured parameter.

trace dissolved oxygen sensor

DO90 – Trace Dissolved Oxygen Analyzer

Prevent Industrial Boiler Corrosion & Scale With

Continuous Trace DO2 Analyzer Accurate to ppb Levels

Ideal For Electric Power Generation Steam Turbine Systems

Irvine, CA—June xx, 2015—Process and plant engineers who need to improve boiler efficiency, reduce maintenance and lower costs will find the new plug-n-play rack mount DO90 Trace DO2 Analyzer from Electro Chemical Devices (ECD) provides continuous precision measurement and alarming of trace dissolved oxygen (DO2) levels in boiler feed water supporting electric power generation steam turbine systems.

Oxygen should only be present in trace quantities in boiler feed water for steam turbine systems because excessive concentrations of oxygen can result in corrosion damage to the components of the boiler’s steam cycle.  Oxygen in the feed water of high-pressure boilers attacks the boiler’s metal construction, leading to severe pitting. In addition, the iron oxide produced by the corrosion leaves iron deposits requiring additional system maintenance.

To remove the oxygen, the boiler feed water is pretreated by thermally or chemically degassing it to achieve oxygen-free water. This state must be maintained throughout the steam cycle. De-aeration is accomplished through the use of physical mediums, including de-aerating heaters or chemical mediums like oxygen scavengers.

Processes that rely only on periodic grab samples to monitor the ppb oxygen concentration in boiler feed water introduce the risk of significant sampling errors.  Such sampling errors can eventually lead to the use of additional costly water treatment consumables and more frequent boiler maintenance cycles that can shorten boiler life.

To prevent these problems, the ECD Model DO90 Trace DO2 Analyzer features a lead silver, galvanic, dissolved oxygen sensor with a durable PFA Teflon® membrane.  The sensor is combined with an intelligent universal transmitter designed for continuous service. The sensor is housed in a rugged, 316L flanged stainless steel body for use in rugged industrial process environments.

Oxygen diffusing through the DO90 sensor’s membrane is reduced at the cathode, producing hydroxide ions that react with the lead ions in the electrolyte to form lead hydroxide.  The anode dissolves more lead ions into the electrolyte, sending electrons to the cathode to reduce any oxygen present. The current flows from the lead anode to the cathode. Under constant conditions, the current is proportional to the oxygen concentration of the medium.

The Model DO90 sensor is a smart, digital device featuring a noise-free digital signal for easy communication.  All data processing is internal to the sensor, and the calibration information is stored in the sensor’s memory.  It also provides integral temperature measurement.

The DO90 sensor features an easily replaceable electrode cartridge, which eliminates the need for messy electrolyte/membrane replacement kits. It offers users a wide measurement range of 0.001 to 20.00 mg/l or ppm/ppb auto-ranging. It operates at a process temperature range of –5 to 50°C and a process pressure range of 0 to 15 psi maximum overpressure. Vacuum operation is not permitted. Highly stable over time, the DO90, with its continuous polarization, drifts less than 1% per month.

The Model DO90 sensor is compatible with ECD’s T80 Universal Transmitter.  It is a single or dual channel transmitter designed for the continuous measurement of pH, ORP, pION, dissolved oxygen, turbidity, conductivity or resistivity in a general purpose industrial environment. The transmitter digitally communicates with the Model DO90 sensor or any ECD Model S80 intelligent sensor, automatically configuring the transmitter’s menus and display screens to the measured parameter.

T80 AquaCult

Modular Analyzer Simplifies Multi-Parameter Monitoring for Low Cost Automated ECD Aquaculture Solutions

Ideal For Control Of Dissolved Oxygen, pH, Nitrate and more

Irvine, CA – May 19, 2015—Aquaculture operators in search of a better way to automate testing for dissolved oxygen (DO), pH, nitrate and other parameters will find the modular plug-n-play T80-S80 Analyzer System from Electro-Chemical Devices (ECD) simplifies operations and lowers total operating costs.

In Aquaculture, the reliable detection of rising levels of DO, pH, nitrates and other parameters is essential to keep fish healthy. These parameters can reach toxic levels quickly or facilitate conditions that lead to disease affecting the health of fish, which requires additional treatments or can cause the death of the fish.

While many operators rely on portable sensors, they require staff time to manually complete the testing on a fixed schedule that can be hard to maintain consistently during their busy work day. The challenge and expense of dedicating staff time to testing becomes incrementally problematic in larger or remote operations.

The installation of fixed analyzer systems, however, such as the rack-mount ECD T80 Universal Transmitter with S80 Intelligent Sensors automates the measurement process. The T80-S80 Analyzer System can be seamlessly integrated with popular control system communication protocols to provide a closed-loop water monitoring and treatment system that maintains water quality for optimum fish growing conditions.

The T80 Transmitter’s own highly intelligent digital protocol simplifies installation set-up and process measurements while also reducing maintenance costs. The two-channel model offers membrane switch navigation, a simple menu structure and soft key menu choices with an easy-to-read 2 ¾ -x- 1 ½ inch LCD display.

The T80 accepts any S80 intelligent sensor or any standard pH sensor with solution ground using the optional T80 input card as an input. It is available with 4-20 mA output with MODBUS RTU on 24 Vdc and 110/220 Vac instruments. The T80 can be configured with optional HART® 7 communication protocol and an optional three alarm relay.

The T80 Transmitter digitally communications with any S80 Sensor, automatically uploading the sensor’s calibration data and configuring the transmitter’s menus and display screens to the desired parameter. S80 Sensors feature a choice of two universal sensor designs: Insertion/Submersion or Valve Retractable with flared end to prevent blow out. They have a rugged ¾-inch OD 316 stainless steel body with a 10-foot cable or an optional waterproof detachable cable assembly.

The versatile S80 DO Sensor features a measurement range from 0.00-20.00 ppm (mg/l) over a temperature range from -10° to 60°C. For pH, the S80 features a measurement range from 0.00 -14.00 pH with a temperature range of -10° to 90°C. To monitor nitrates, the S80 Sensor has a measurement range of 0.1 ppm to 14,000 ppm (3-11 pH), 7×106 molar to 1 molar NO3 over a temperature range from 0° to 40°C.

With the S80 Sensors, the economical auto clean option includes a solenoid actuated spray cleaner using either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle. The auto clean option pays for itself by reducing time consuming manual maintenance routines, which frees staff for other more productive activities.

Combining ease of set-up, modular design and low maintenance, the T80-S80 Analyzer System is ideal for demanding aquaculture applications. From single point of measurement to monitoring multiple parameters, the flexible T80-S80 Analyzer System is an economical automation tool for economical aquaculture production operations.
