Measure Free Chlorine Without Compromising Quality or Time

These membrane-covered amperometric sensors are used to measure the concentration of free chlorine. The following anorganic chlorination agents can be measured: chlorine gas (Cl₂), elec-trolytically generated chlorine, sodium hypochlorite (NaOCl, chlorine bleaching solution), calcium hypochlorite (Ca(OCl)₂), or chlorinated lime (Ca(OCl)Cl).

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