Introduction widely used in environmental protection, water quality monitoring, agriculture, forestry soil, teaching and research departments. 
 Product details after the pretreatment of water samples or water samples into the culture bottles, while the absorption of the cup in the bottle into the carbon dioxide absorbent (NaOH), and the flask sealed and placed in HY-1A-type biochemical incubator When the sample at 20 ± 1 ℃ for 五日 cultured under the conditions of constant temperature after a certain stirring speed, the bottle of water samples for biological oxidation. Into organic nitrogen, carbon and sulfur oxides, and absorption of carbon dioxide gas is sodium hydroxide, and culture bottles keep the upper space of the oxygen supply of the oxygen demand of microorganisms in water samples, culture bottles had a pressure difference, mercury glass tube by detecting the height of the water sample can be calculated within a specified period measured BOD values.
