ROCKER COD Detector model CD200 198200-02

The CD 200 COD Detector (model CD200, 198200-02) is a portable chemical oxygen demand (COD) photometric detector for rapid determination of COD concentrations using heated vials. It reads preprogrammed reagent curves from multiple reagent brands or user-defined curves, returns a COD result in 3 seconds, and stores measured data for later review. Primary use cases include wastewater testing at industrial sites, water quality monitoring of surface and groundwater, and environmental monitoring of lakes, ponds, and rivers.

Key Features:

• Model: CD200; Part number: 198200-02 (EU plug)
