One Application fields of high concentration sewage CODcr-1H COD tester:

Application domain keywords:

The CODcr-1H COD 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 can be widely used in water plants, food, chemical, metallurgical, environmental protection, and pharmaceutical industries, and is a commonly used laboratory instrument.

II Detection principle of CODcr-1H COD tester for high concentration wastewater:

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. Chemical oxygen demand is often used as a comprehensive indicator to evaluate the relative content of organic matter and is one of the indicators for implementing total emission control in China.
