1、 Product Overview Chemical Oxygen Demand (COD) refers to the amount of oxidant consumed when treating water samples with potassium dichromate as an oxidant under strong acid and heating conditions, expressed in mg/L of oxygen.

The economical COD type tester adopts a rapid digestion method, with a simple, fast, and economical operation process. The measurement results have good comparability with traditional titration methods. This instrument has a range of 0-150mg/L and is widely used for detecting effluent from sewage treatment plants. The range of 0-5000mg/L is widely used for sewage detection in sewage treatment plants, food, chemical, metallurgical, environmental protection, and pharmaceutical industries. It is a commonly used laboratory instrument.

The technical parameter number displays the range corresponding to reagent 1COD1505-1500mg/LA1, A2，A3，D2COD5000300-5000mg/LC1，C2，C3，D
