Liquiline CM444R is a state-of-the-art transmitter for pH, ORP, conductivity, oxygen, chlorine, turbidity, sludge level, SAC, nitrate and many other parameters.

An optional display enables configuration, maintenance and operation of the measuring point on-site. ©Endress+Hauser

An optional display enables configuration, maintenance and operation of the measuring point on-site.

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.

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.

Expandable multiparameter DIN-rail and cabinet device for all industries

Liquiline CM444R is a digital multiparameter transmitter for process monitoring and control in all applications - even where mounting space is limited. You save time and money through fast and simple installation, operation and handling. The 4-channel controller can be extended to accommodate up to 8 sensors at any time to fit the needs of your process. Liquiline CM444R provides you with all the benefits of a best-in-class transmitter platform from clever simplicity to maximum process safety.
