Conventional Pollution Online Monitoring Instrument
Permanganate Index Online Analyzer
product details

Product model: CODMn-8000


System overview


After the sample is filtered, it is sent to the digestion tank. At the same time, the analyzer controls the heating device for heating. Potassium melanoate is added to the digestion tank in sequence, and the concentrated sulfuric acid is digested at 100℃. The digestion time can be selected according to the raw water quality. By measuring the absorbance to convert the high Bate index concentration of the water to be measured, the system will automatically clean the entire measuring system with pure water after measurement to ensure accurate measurement next time.


Method classification


· Acid high potassium acid method: used for conventional surface water to drink groundwater;

· Alkaline high potassium acid method: used for unconventional water bodies such as seawater;


System features


· Maintenance Free Design

The water sample pre-treatment device adopts a maintenance free design, which can ensure that the maintenance cycle of the pre-treatment device exceeds six months;
