    Introduction:
    70-type differential pressure direct reading BOD analyzer is the use of air pressure difference method for the determination of BOD a new instrument, its simple operation, can provide accurate and chemical dilution method comparable to accurate measurement results, intuitive readings, use and maintenance Convenience. Widely used in environmental monitoring, petrochemicals, health care, teaching and research departments of water quality monitoring, the majority of analysts is a powerful tool.
    Pre-selected range and volume range of good volume of water samples into the flask, continuous stirring in the host mixer. Place the host and flask in the incubator. Incubate the incubator at a temperature of 20 ° C ± 1 ° C until the sample is incubated for five days at a constant temperature. The water sample in the flask ensures sufficient dissolved oxygen for the biochemical reaction of the microorganisms with continuous agitation. Organic matter in water samples undergo biological oxidation to convert nitrogen, carbon and sulfur oxides. During this process, the only gaseous carbon dioxide that has spilled from the water sample is absorbed by sodium hydroxide (or potassium hydroxide). At this point, the decrease in air pressure in the flask corresponds to the dissolved oxygen content of the microorganisms, ie, the BOD5 value of the water sample is proportional to the reduction of air pressure in the bottle, so the value of BOD5 can be determined from the air pressure reduction value, Increase or decrease the amount of sample taken
    Technical indicators
