Liquiline CM442 is a state-of-the-art transmitter for pH, ORP, conductivity, oxygen, chlorine, turbidity, sludge level, SAC, nitrate and many other parameters.

Heartbeat Technology offers diagnostics, verification and monitoring of the measuring point. ©Endress+Hauser

Liquiline transmitters with Heartbeat Technology offer status-oriented maintenance and easy verification of the measuring point and help you to carry out optimization measures.

The transmitter's modular design allows you to easily upgrade and add functionality at any time. ©Endress+Hauser

Stay flexible with the Liquiline CM442 transmitter: its modular design allows you to easily upgrade and add extra functionality at any time (digital fieldbuses, number of channels, relays, etc.).

Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.

  • Liquiline CM442 is a state-of-the-art transmitter for pH, ORP, conductivity, oxygen and more.
  • Heartbeat Technology offers diagnostics, verification and monitoring of the measuring point.
  • The transmitter's modular design allows you to easily upgrade and add functionality at any time.

Expandable multiparameter field device for all industries

Liquiline CM442 is a digital multiparameter transmitter for process monitoring and controlling in any application. The 1-/2-channel controller saves you time and money by offering seamless system integration, simple operation and a reduced need for spare part stock. Liquiline CM442 provides you with all the benefits of a best-in-class transmitter platform from clever simplicity to maximum process safety.
