Disinfection Sensors

Walchem's amperometric disinfection sensors offer a cost effective and reliable solution to your disinfection control requirements. Compatible with the WDIS and WebMaster® series controllers, the sensors continuously and directly measure the chemical concentration, without the use of reagents.

We offer sensors, in varying ranges of concentration, for free chlorine/bromine, total chlorine, chlorine dioxide, ozone, peracetic acid and hydrogen peroxide. Whether the application is a cooling tower, food and beverage, drinking water, wastewater, or swimming pool, these sensors are the ideal solution.

  • Low maintenance - no costly reagents or tubing to replace
  • Broad range of applications - wide variety of oxidizers and measurement ranges
  • Fast response - continuous measurement technique
  • No waste - the sample can be returned to the process
