BOD equipment is designed for Biochemical Oxygen Demand ( BOD analysis) in water and wastewater samples according to official organizations.

Biochemical Oxygen Demand, commonly known as BOD analysis, is a chemical procedure for determining the amount of dissolved oxygen consumed by aerobic biological microorganisms in water. The analysis is carried out on a given water sample at certain temperature over a specific period. The results are most commonly expressed in milligrams of oxygen consumed per liter of sample at a constant temperature of 20 ° C over a 5 day incubation period ( BOD5) , or during complete oxidation obtained after a maximum period of 30 days ( BODultimate) .
BOD analysis is widely used as an indication of the organic quality of water and the degree of organic pollution of water.
