Measuring principle
The water sample to be tested is pre treated and subjected to high-temperature and high-pressure digestion in an acidic environment of potassium permanganate. The reducing substances in the water will consume the potassium permanganate content, and the degree of color change is proportional to the content of reducing substances in the water sample. The analyzer detects this color change and converts it into a COD Mn value output.
