Non-Membrane Disinfection Sensor

Disinfection non membrane sensors, designed for high pressure, high temperature applications

Non-membrane chlorine/bromine and chlorine dioxide sensors comprising amperometric sensor assembly, cable, and a flow cell. They measure the disinfectant level in drinking water. The disinfection of hot potable water systems as currently required by the new ASHRAE standards is up to 70°C (158 °F), especially for hospitals, schools, and universities.

Disinfection control

Cost effective and reliable solutions for disinfection control requirements. Compatible with the W100, W600, W900 and Intuition series controllers, the sensors continuously and directly measure the chlorine/bromine or chlorine dioxide chemical concentration without the use of reagents.

Amperometric sensors

Amperometric sensors perform best in drinking water or any clean water application with near neutral pH, and are typically used in higher pressure and/or temperature installations. Whether the application is a cooling tower, food and beverage, drinking water, wastewater, or swimming pool, these sensors provide stable, accurate measurements with low maintenance. Walchem controllers with amperometric chlorine sensors can be used for reporting chlorine residual measurements in accordance with EPA Method 334.0.

Features

  • Free chlorine/bromine and chlorine dioxide 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
