Chlorine sensors for different environments

Electro-Chemical Devices has developed a series of sensors for chlorine analysis that are designed to cost-effectively fit into chlorine monitoring systems in a wide variety of aqueous environments. The FCA- 22 Free Chlorine Sensor, TCA-22 Total Chlorine Sensor and CDA-22 Chlorine Dioxide Sensor are high-accuracy amperometric sensors suitable for fresh water applications including monitoring of industrial cooling and rinse water, drinking water and wastewater.

The FCA-22 precisely measures free residual chlorine from 0.05 to 20.0 ppm Cl2, 5 to 9 pH and at temperatures from 0 to 50°C. The TCA-22 is designed for samples containing chlorine in the range of 0-20 ppm, operating at a temperature range of 0-45°C. Its amperometric sensor features a three-electrode design that measures all chlorine species in the water, combined chlorine and free chlorine.

The CDA-22 Chlorine Dioxide Sensor, a polarographic amperometric sensor with gold cathode and silver chloride anode and PTFE membrane, is designed to measure chlorine dioxide in concentrations ranging from 0.05-20 ppm CIO2 and operates at a wide temperature range of 0 to 50ºC. It can run for up to one year between electrolyte/ membrane changes.
