BOD-573 BOD Analyzer

BOD is a kind of environmental pollution index, which is mainly used to determine the pollution status of organic matter in water body; it can also be used as a basis to evaluate the operation efficiency of sewage treatment plant, so as to find the right treatment method.
The method is based on pressure measurement in a closed system: microorganisms in the sample consume the oxygen and form CO2 . This is absorbed by NaOH, creating a vacuum, which can be read directly as a measured value in mg/l BOD.
