Sustainability Matters, TC-80 Total Chlorine Analyser, Feb. 1

The plug-n-play TC-80 Total Chlorine Analyser from Electro-Chemical Devices (ECD) offers simplified monitoring for water and treatment processes, easy installation and less maintenance for lower ownership costs. The analyser monitors total chlorine in drinking water, rinse water, cooling water or other fresh water samples from 0.05–20 ppm chlorine as the standard range or 0.005–2.000 ppm with the low-range sensor.

The advanced panel-mount design includes built-in flow control, eliminating the need for complicated pressure regulators and rotameters. Built-in automatic pH compensation also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs.

The device is ready to use after connecting the sample and drain lines, then the power and outputs. The TC-80 is calibrated at the factory before shipment, with calibration accomplished by DPD comparison.

The TCA sensor is a three-electrode amperometric sensor with a gold cathode, silver halide anode and 304 SS counter electrode. The TC-80’s pH sensor provides accurate compensation for samples between pH 4 and pH 12, eliminating the need for expensive sample conditioning systems to control the pH of the solution.

Amperometric chlorine sensors are flow sensitive — the minimum required flow by the sensor is 0.5 ft/s, above this value the output is virtually flow independent. A ‘constant head’ flow controller maintains the optimum flow by the sensor over a wide range of incoming sample flow rates. The minimum flow required is 10 gal/h, and the maximum flow rate is 80 gal/h with the sample going to drain at atmospheric pressure.

The device is available with either 110–240 VAC or 24 VDC power.
