Products are widely used in environmental protection, water quality monitoring, agriculture, forestry soil, teaching and research departments. 
 BOD5 980 type digital detector design using the principle of air pressure from France, when the sample at 20 ± 1 ℃ for 五日 cultured under the conditions of constant temperature, after biological oxidation of organic matter into nitrogen, carbon and sulfur oxide materials, and produce carbon dioxide absorbed by sodium hydroxide, culture bottles to reduce the pressure by the change in pressure sensor into electrical signals, which can detect the sample BOD5 value.
