Field of application
Liquiline System CA80HA offers precise online analysis of water hardness in drinking water and process water. It helps you to optimize the control of water softening processes in drinking water applications and the optional dilution module allows water hardness measurements with concentration up to 1600 mg/l. 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 classify water hardness in drinking water
To ensure process water quality in production plants
For monitoring process water, e.g. in pure and ultrapure water or desalination plants, requiring a lower limit of detection, please refer to the low range analyzer Liquiline System CA82HA.
Benefits
The water hardness analyzer uses the colorimetric 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
Drive connectivity: Liquiline Edge Module CYY7 transfers process data to Netilion, independently of the fieldbus. This allows remote overview and the use of IIoT services. It’s available in new products or as upgrade to installed Liquiline platforms.
