COD-571 Chemical Oxygen Demand AnalyzerDetailed product description：

COD-571 Chemical Oxygen Demand Analyzer Instrument Features:

Chinese menu display, easy to operate
Using potassium dichromate colorimetric method
Directly read the COD result without the need for titration or other methods for analysis
Using PP40 printer, test results can be printed

COD-571-1 type
The digestion device has a compact structure and can simultaneously perform 21 sample digestion reactions, reducing energy consumption

Low analysis cost and reduced secondary pollution
The digestion temperature can be set arbitrarily between 50 ℃ and 150 ℃, and there is an over temperature alarm device
The digestion time can be set arbitrarily from 0 to 120 minutes, and the reaction will automatically shut down after completion, making it easy to operate
