Reagent-less, Digital FC80 Free Chlorine Analyzer Minimizes Maintenance & Cuts Cost of Ownership
Anaheim, CA—August 17, 2022—Busy engineers and technicians bogged down by the monitoring and frequent replacement of costly sensor reagents will find that they can save time and money with the FC80 Free Chlorine Analyzer from Electro-Chemical Devices (ECD)
The digital plug-n-play, highly intelligent FC80 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 with ECD’s highly intelligent S80 pH Sensor eliminates the need for expensive reagents to reduce time-consuming maintenance and high analyzer sensor life-cycle costs.
Highly accurate and reliable, the dependable FC80 Analyzer monitors free chlorine in drinking water from 0.05 – 20 ppm chlorine as the standard range or 0.01 – 5.00 ppm with the low range sensor. The FC80 is compliant with EPA method 334.0 for measuring drinking water. It also supports industrial applications: rinse water, cooling water or other fresh water sampling.
Everything needed comes with the FC80’s complete panel mount design kit, incorporating a constant head flow control device, the S80 pH sensor, the FC80 chlorine sensor and ECD’s T80 analyzer/transmitter. Connect the sample and drain lines, connect the power and outputs, and it is ready to use. Calibration is accomplished by DPD comparison.
The intelligent T80 Analyzer from ECD is designed with an amperometric sensor. This sensor measures only the only the hypochlorous acid component of the free chlorine sample and the analyzer calculates the balance using either the measured pH or a user defined fixed value. The pH sensor provides accurate compensation for samples between pH 6 and 9, thus eliminating expensive sample conditioning systems to control the pH of the solution.
User will find the free chlorine necessary for disinfection exists in solution as a pH dependent ratio of hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10). Chlorine has been a popular disinfectant for water treatment to ensure public health. Disease causing organisms such as Cholera, Hepatitis A, Typhoid Fever and Dysentery are eliminated with Chlorine, along with slime bacteria, algae and molds that can grow in water storage facilities such as reservoirs and storage tanks.
Over the past decades, there have been several other methods developed to measure chlorine in drinking water applications. Colorimetric systems, for example, have been popular, but require the use of reagents that must be replaced monthly in order to ensure accurate measurement. With its amperometric sensor design, the FC80 eliminates the need for expensive reagents and offers an economical operating cost for municipal water districts that must manage tight budgets.
The go-anywhere FC80 Analyzer is available with either 110-240 VAC or 24 VDC power. Its highly intuitive user interface parameters can 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 a MODBUS RTU.
Ideal for dirty or nutrient-rich environments, the FC80 is available with an Auto Clean option 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.
