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.

Key Benefits

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

The disinfection of hot potable water systems as currently required by the new ASHRAE standardsUp to 70 °C (for Hospitals, schools, universities, …)

High pressure sample loops where the water cannot be discharged to open atmosphere

  • Up to 8 bar (117 psi)
  • Hot tubs, cooling towers

Featuring

  • Free Chlorine and ClO2 sensors
  • Designed for higher pressure and temperature, clean water applications
  • Amperometric 3-electrode sensors
  • The measuring and counter electrodes are in direct contact with the sample
  • The reference electrode is isolated from the water by an electrolyte-filled housing
