The BOD meter produced by our company is designed according to the principle of differential pressure measurement. It simulates the biodegradation process of organic matter in nature. In the sealed culture bottle, the oxygen in the air above the culture bottle continuously replenishes the dissolved oxygen consumed by the decomposition of organic matter in the sample. The CO2 produced during the degradation of organic m atter is removed, which changes the air pressure in the culture bottle. By monitoring the change of air pressure in the culture bottle, the biochemical oxygen demand (BOD) value of the sample is calculated.
The BOD meter produced by our company can select a culture time of 1-30 days and test six water samples at the same time. During the test, the current BOD value tested is directly displayed on the screen, and the current test data can be viewed at any time. The instrument has an automatic storage function, and the test result data can be viewed at any time. The instrument also has a wireless printing function, which can print test data. The instrument can store 10 years of BOD5 result values, and the test data can be directly transmitted to the computer via wireless transmission.
