◎ Automatic cleaning function

Measurement principle:

After filtering the sampleAfter being pumped into the digestion tube, potassium dichromate, silver sulfate, sulfuric acid, and mercury sulfate were added and heated to 175 ℃. After complete digestion, the analyzer measured the OD value of the generated green substance at 460nm and calculated the COD concentration in the sample based on the correction factor stored in the analyzer.
