Product Description

CODmn water quality online automatic monitor cabinet type

Product Overview:

CODmn refers to the mass concentration of the oxidant consumed when oxidiorganic matter and inorganic reducing substances in water samples with strong oxidant under certain conditions. CODmn is also an important indicator to reflect the degree of pollution of organic matter and inorganic reducing substances in water bodies.
The analyzer can work automatically and continuously when set unattended for a long time according to the site, and is widely used for surface water and other occasions. According to the complexity of the field test condition, the corresponding pretreatment system can be selected to ensure the reliability of the test process, the accuracy of the test results, and fully meet the site needs of different occasions.

Measurement method:
Manganese COD uses permanganate as an oxidant, and is heated in a water bath for 20 minutes. Potassium permanganate takes the amount of organic matter decomposition in sewage as the index of pollutants in sewage.
