Brief introduction:
890 type microcomputer principle of BOD5 meter air pressure difference method is used to design and become, when the sample to be tested in 20 + / - 1 ℃ under the condition of constant temperature, after five days training through biological oxidation, organic matter into nitrogen, carbon and sulfur oxides, and produces carbon dioxide absorbed by sodium hydroxide, decrease pressure in the culture bottle. Measuring pressure difference, through the microcomputer data processing, display and print the measured results. Technical indicators:
