HACH BODTrak II Biochemical Oxygen Demand (BOD) Analyzer

Biochemical oxygen consumption（BOD）The amount of oxygen consumed when organic matter in water is biodegraded by microorganisms is a comprehensive indicator reflecting the content of organic pollutants in water. It is mainly used to monitor the pollution status of organic matter in surface water bodies, determine the organic pollution load of sewage and wastewater, and evaluate the biodegradability of sewage and wastewater.HACH BODTrak IIBiochemical oxygen consumption analyzer（BODThe measuring instrument adopts the pressure difference methodBODMeasurement principle, simulating the biodegradation process of organic matter in nature, the oxygen in the air above the test bottle continuously supplements the dissolved oxygen consumed in the water, and the organic matter generated during the degradation processCO2Absorbed by potassium hydroxide in the sealed lid, the pressure sensor constantly monitors the changes in oxygen pressure in the sampling test bottle. In biochemical oxygen consumptionBODEstablish a correlation between the amount of oxygen consumed in the test bottle and the gas pressure, in order to accurately performBODBiochemical oxygen consumption measurement, with test results displayed graphically on the screen,BODThe value will bemg/LDisplay directly for the unitBODOn the screen of the measuring instrument.
