Overview
Brief description: TW-5278 BOD analyzer (direct reading) injects water samples or pre treated water samples into a culture bottle, and at the same time, (NaOH) is placed in the absorption cup at the bottle mouth. Then, the culture bottle is sealed and placed in a biochemical incubator. When the tested sample is at 20amp# 177; After five days of constant temperature cultivation at 1 ℃, the water sample in the bottle undergoes a biological reaction at a certain stirring speed. The gas in the upper space of the culture bottle continuously supplies the required amount of microorganisms in the water sample, resulting in a pressure difference inside the culture bottle,
Product Details
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.
