Field of application
Liquiline System CA80HA offers precise online analysis of water hardness in drinking water and process water. It helps you optimize the control of water softening processes such as ion exchange or reverse osmosis and ensures optimal quality of products that are influenced by water hardness. The analyzer's automatic calibration and cleaning and its low reagent consumption reduce operating costs while advanced diagnostics with remote access ensure consistent process safety.
Liquiline System CA80HA supports you in monitoring total water hardness:
To optimize reverse osmosis and ion exchanger systems
To classify water hardness in drinking water
To ensure process water quality in production plants
Benefits
The water hardness analyzer uses the phthalein purple method, ensuring direct comparability to lab results
Fast commissioning with plug & play thanks to Memosens technology and user-friendly operation
Reduces operating costs thanks to automatic calibration and cleaning, low reagent consumption and long reagent lifetime with optional cooling module
Easy upgrade of functionality to a complete measuring station - by adding modules and connecting Memosens sensors.
Advanced diagnostics with remote access for increased process safety
Easy, tool-free maintenance
