Description

Liquiline System CA82HA enables colorimetric online analysis of low range hardness concentration with a limit of detection (LOD) as low as 0.02 mg/l. It helps operators to increase efficiency, e.g. by reducing deposits on heat exchangers. Moreover, Liquiline System CA82HA helps to avoid damage on capital intensive equipment like turbines. The analyzer supports ensuring the quality (e.g. steel, paper, tires) thanks to reliable pure and ultrapure water analysis.

Field of application

Liquiline System CA82HA supports you in monitoring the total hardness of water with a low limit of detection in the following applications:

  • Monitoring of boiler feed water, condensate, water/steam circuit
  • Pure and ultrapure water analysis
  • Reverse osmosis and desalination plants


For monitoring of drinking water processes or if a wider measuring range is required, please refer to the water hardness analyzer Liquiline System CA80HA.
