High-Performance Water Analysis Controller for Industrial Process Monitoring
The Endress+Hauser CM444 Liquiline is a modular 4-channel multiparameter controller designed for continuous water quality monitoring across industrial and environmental applications. Built on the Liquiline platform, it allows seamless integration of digital sensors and ensures accurate, stable, and real-time measurement for wastewater treatment plants, power plants, desalination systems, food and beverage production, and chemical industries.
The Liquiline CM444 supports up to four Memosens digital sensors, enabling simultaneous measurement of parameters such as pH, ORP, DO, conductivity, turbidity, chlorine, nitrate, and more. With intelligent diagnostics, automatic sensor recognition, and a robust communication interface, the CM444 ensures high measurement reliability and operational continuity.
This controller is designed for scalable expansion and long-term reliability, making it a trusted choice for quality monitoring in critical processes.
Connect up to 4 Memosens sensors in any combination.
Easily upgradeable to additional channels.
Contactless, corrosion-free digital data transmission.
