BODTrak II analyzer biochemical oxygen demand (BOD meter) differential pressure method BOD measurement principle, simulate the natural process of biodegradation of organic matter above the test bottle oxygen in the air constantly replenished water consumed oxygen, generated in the process of organic matter degradation CO2 is absorbed by the sealing cap potassium hydroxide, pressure sensors constantly monitor the oxygen bottle sampling test pressure changes. Biochemical oxygen demand BOD (which corresponds to the amount of oxygen consumed bottle test) to establish the correlation between the gas pressure to accurately perform BOD BOD measurement, the test results are displayed graphically on the screen, BOD
