Get reliable chlorine concentration readings every time

These membrane-covered amperometric sensors are used to measure the total chlorine concentration in water.

The sensors acquire the total of “free chlorine” (chlorine gas, hypochlorite, etc.) and “combined chlorine” (chloramine, organically combined chlorine).

The sensors are not suitable for detecting the absence of chlorine.

The sensors’ integrated electronics provide a temperature-compensated current signal (4 to 20 mA) for the variant with an analog output signal, and a Modbus RTU signal for the variant with a digital interface. A downstream device (indicator, controller, recorder, PLC, etc.) is used for calibration.

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