Walchem Conductivity Electrodes

Contacting Conductivity Sensors Contacting Conductivity Sensors

Contacting conductivity sensors are ideal for use in cooling towers and boilers, reverse osmosis equipment, and other non-oily applications.

Key benefits:

Conductivity electrodes are devices that measure the conductivity of a liquid which means the ability of the fluid to conduct electric current. There are conductivity sensors that are electrodeless, and they measure conductivity using non-contact toroidal technology. Walchem specialises in manufacturing high-quality water treatment sensors and accessories for a broad range of applications. We offer contact-based conductivity sensors using electrodes and non-contact electrodeless conductivity sensors.

  • Available as low cost CPVC contacting and non-contacting toroidal sensors, or stainless steel sensors for boiler applications
  • In-line or submersion mounting (non-boiler applications)
  • Easy installation & electrode replacement
  • Low cost CPVC sensor available for temperatures below 80 degree C
  • PEEK™ sensor construction provides excellent chemical resistance and with stands high temperature solutions, ideal for plating applications
  • Toroidal sensor technology eliminates contamination/ calibration issues that direct contacting sensors are prone to
  • Boiler conductivity electrode rated to 250 PSI/ 200 degree C and can be located up to 250 feet from the controller
  • General purpose contacting conductivity sensor, e.g. for RO systems, boiler condensate, etc
