870 Biochemical Oxygen Demand TesterProduct features:

The 870 direct reading BOD5 analyzer is designed based on the principle of air pressure difference method. When the tested sample is incubated at a constant temperature of 20 ± 1 ℃ for five days,After biological oxidation, some substances are transformed into oxides of nitrogen, carbon, and sulfur, and produce carbon dioxide gas that is absorbed by sodium hydroxide. At this time, the culture bottleThere is a pressure difference inside. By detecting the height of mercury in the glass tube, the BOD5 value of the water sample can be calculated, which can accurately provide information on chemical dilutionComparability of interpretation measurement results.
