1、 Product Introduction:

EF-BODType direct readingBODThe measuring instrument is easy to operate,Can provide accurate measurement results comparable to chemical dilution methods;Intuitive reading;Easy to use and maintain;Widely applicable. Laboratory testing in various industries, sewage treatment, universities, and research institutions

2、 Measurement Overview:
Inject the water sample or pre treated water sample into the culture bottle, and place the carbon dioxide absorbent in the absorption cup at the bottle mouth(NaOH)Then seal the culture bottle and place it in a dedicated biochemical incubator. When the tested sample is in20±1After five days of constant temperature cultivation at ℃, the water sample in the bottle undergoes biological oxidation reaction at a certain stirring speed. Organic matter is transformed into oxides of nitrogen, carbon, and sulfur, producing carbon dioxide gas that is absorbed by sodium hydroxide. The oxygen in the upper space of the culture bottle continuously supplies the oxygen demand of microorganisms in the water sample, creating a pressure difference inside the culture bottle. By detecting the height of mercury in the glass tube, the water sample's oxygen demand during the specified measurement period can be calculatedBODValue.
