Product Overview:
The EasyPREP COD-200 fully automatic chemical oxygen demand analyzer from Canada can automate the entire process of digestion, sample time tracking, shaking, analysis, data transmission, and storage. Users only need to place the COD reagent tube with the sample into the sample rack, and the instrument can complete automatic digestion, shaking, and analysis in real-timeDisplay measurement progress and concentration calculation.COD-200 is compatible for analyzing dichromate saltsPotassium permanganate index and turbidity detection. Complies with HJ/T399-2007, HJ924-2017, and EPA410.4 method standards, greatly improving laboratory performancepersonnelWork efficiency.
