Nitrite 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.

  • Liquiline System CA80NO - Nitrite analyzer for drinking water, mineral water, wastewater
  • Liquiline System CA80NO nitrite analyzer with cooling for extended reagent lifetime

Colorimetric system for monitoring of drinking water, mineral water or raw water for food production

Liquiline System CA80NO offers precise, regulation-compliant online measurement of nitrite. It supports you in meeting the specified limits in drinking water, mineral water or food production. Like all Liquiline System analyzers, it enables plug & play of up to four Memosens sensors – minimizing the installation effort. Automatic calibration and cleaning and the low reagent consumption reduce operating and maintenance costs. Advanced diagnostics with remote access ensure process safety.
