Field of application

The Liquiline CM442 transmitter allows you to connect up to 2 Memosens sensors of your choice from over 12 measurement parameters. It offers automatic sensor recognition, easy operation, and standardized spare parts with all other devices of the Liquiline platform. With its inputs, outputs, controllers, and math modules, you can even control cleaning systems or dosing pumps.

Features

  • One transmitter for all parameters and applications: pH, ORP, conductivity, oxygen, chlorine, turbidity, sludge level, SAC, nitrate,...
  • Connect up to 2 Memosens sensors (depending on the chosen configuration).
  • Versions with Heartbeat Technology enable status-oriented maintenance and easy verification of the entire measuring point.
