Chromate concentration in a liquid can be measured using the colorimetric measuring principle. This video shows what it is about and how this measuring principle works.

Colorimetric system for the monitoring of industrial wastewater and optimization of process control

Liquiline System CA80CR offers highly accurate online measurement for optimized chromate removal in industrial wastewater. It supports you in achieving environmentally compliant electroplating and tanning processes. Like all Liquiline System analyzers, CA80CR enables plug & play of up to four Memosens sensors - minimizing the installation effort. Automatic calibration and cleaning plus advanced diagnostics with remote access ensure consistent process safety.
