Analyzer for chemical oxygen demand in environmental monitoring, industrial and municipal wastewater

Liquiline System CA80COD offers constant online measurement of the chemical oxygen demand (COD). It supports you in monitoring the cleaning capacity of wastewater treatment plants and enables load-based billing for industrial dischargers. Automatic calibration and cleaning save operating costs while advanced diagnostics with remote access help to provide process documentation to authorities. The COD analyzer's software-controlled safety functions ensure the highest level of occupational safety.
