Field of application

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.

Liquiline System CA80PH supports you in optimizing the cleaning capacity of wastewater treatment plants. It monitors and controls:

Precipitant dosing in aeration basins
Wastewater treatment plant outlets

In industrial applications, Liquiline System CA80PH is used for the monitoring of cooling water cycles.

Benefits

Fast commissioning and plug & play thanks to Memosens technology and user-friendly operation
Easy upgrade of functionality - even to a complete measuring station - simply by adding modules and connecting Memosens sensors
Advanced diagnostics with remote access for increased process safety
Reduced operating costs through automatic calibration and cleaning and long reagent shelf life with cooling module
Available with both standardized measuring methods covering all applications: Molybdenum blue method and Molybdate Vanadate yellow method
