Liquiline CM448 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 add functionality at any time. ©Endress+Hauser

Stay flexible with the Liquiline CM448 transmitter: its modular design allows you to easily add functionality at any time (e.g. digital fieldbuses, 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 CM448 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 add functionality at any time.

Flexible multiparameter field device for all industries

Liquiline CM448 is a digital multiparameter transmitter for process monitoring and controlling in any application. The 8-channel controller saves you time and money by offering seamless system integration, simple operation and a reduced need for spare part stock. Adapt the controller exactly to your measuring task and connect 1 to 8 sensors as desired. Liquiline CM448 provides you with all the benefits of a best-in-class transmitter platform from clever simplicity to maximum process safety.
