1TW-5278 BOD analyzerbrief introduction

Inject the water sample or pre treated water sample into a culture bottle, and place (NaOH) in the absorption cup at the bottle mouth. Then seal the culture bottle and place it in a biochemical incubator. After the tested sample is incubated at a constant temperature of 20 ± 1 ℃ for five days, the water sample in the bottle undergoes a biological reaction at a certain stirring speed. Organic matter is converted into carbon and sulfur compounds, and the gas in the upper space of the culture bottle continuously supplies the required amount of microorganisms in the water sample. A pressure difference is generated inside the culture bottle. By detecting the height of mercury in the glass tube, the BOD value of the water sample during the specified measurement period can be calculated.
