The BOD tester is designed based on the principle of differential pressure method, which simulates the bio-degradation process of organic matter in nature. In the sealed culture bottle, the oxygen in the air above the culture bottle continuously supplements the dissolved oxygen consumed by the decomposition of organic matter in the sample. The CO2 produced in the process of organic degradation was removed to change the air pressure in the culture flask. By monitoring the change of the air pressure in the culture flask, the BOD value of the sample was calculated.
Test six water samples at the same time for 1-30 days culture time.
During the test, the current BOD value is displayed on the screen.

Store BOD5 results for 20 groups.
