Trace sensor for drinking and industrial water treatment

CCS241 is the analog sensor for trace measurement of chlorine dioxide. It delivers reliable values even if fluctuations in flow or conductivity occur and allows control of the disinfection loop so that the water is free of germs. At the same time, the sensor is designed for long calibration and service intervals reducing your maintenance effort.

  • Benefits

    • Recalibration intervals approx. 1 to 4 months under constant operating conditions

    • Easy membrane replacement thanks to prefabricated membrane cap

    • Measured values are not affected by conductivity fluctuation

    • Measurement virtually independent of flow rate in...

  • Field of application

    CCS241 measures chlorine dioxide in:
