Measure Chlorine Dioxide and Ozone with accuracy

These membrane-covered, amperometric sensors are used to measure the concentration of chlorine dioxide or ozone in aqueous solutions.

The sensor for chlorine dioxide can be used to measure chlorine dioxide from chlorite/chlorine and chlorite/hydrochloric acid plants. The sensor for ozone can be used to measure electrolytically generated ozone among other things.

The sensors are not suitable for detecting the absence of chlorine dioxide or ozone. Depending on the type, the electronics integrated in the sensors provide an analog, temperature-compensated current signal (4 to 20 mA) or a digital Modbus RTU output signal.

The sensors can be connected directly to indicating devices/transmitters/controllers. They supply the sensors with voltage and allow for easy calibration of the measuring system.
