Instant alarm messages sent out when threshold is reached.  Graphics of sensor values and control output status are easily accessed on screen or on web page.


Our Walchem controllers provide universal sensor inputs on the controller functions. This gives our analyzers the ability to monitor various types of applications in water treatment.

Easy Installation

Analyzers are built as a package on a panel and provides simple plug-and-play installation. The controller included provides a large touchscreen display with icon-based programming for simple setup.

Amperometric Sensors

Amperometric sensors utilize two dissimilar metals (one as an anode and one as a cathode) behind a membrane to measure the oxidation-reduction taking place. Buffered electrolytes allow the sensor the ability to measure the parameter over a wider pH range. The sensor is able to continuously monitor the water without intervals or reagents.

Our amperometric sensors can continuously detect key water charatersics in real-time. Our Sensors detect:

  • Chlorine
  • Ph
  • Peracetic acid
