Liquiline System CA80HA

Summary

Product identification

The Liquiline System CA80HA is a wet-chemical analyzer designed for the near-continuous determination of total hardness concentration in liquid media. It utilizes a colorimetric measuring principle.

Application

The analyzer is suitable for:

• Optimization of reverse osmosis systems and ion exchangers.
• Classification of drinking water hardness levels.
• Ensuring process water quality in production plants.

Measuring principle

The Liquiline System CA80HA employs a colorimetric method. A reagent is added to the sample, causing a color change proportional to the total hardness. A multispectral photometer measures the light absorption at a specific wavelength (568 nm) to determine the concentration. A reference measurement is performed to compensate for interference.
