Colorimetric system for wastewater monitoring and optimization of process control

Liquiline System CA80PH offers online orthophosphate measurement for precise dosing of precipitants in wastewater treatment. As all Liquiline System analyzers, it enables plug & play of up to 4 Memosens sensors - minimizing the installation effort. Automatic calibration and cleaning and the low consumption of reagents save you operating costs. Advanced diagnostics with remote access ensure process safety and support you in providing process documentation to the authorities.
