JQ-880Type digitalBOD₅Meter

JQ-880Digital BOD₅The measuring instrument is designed based on the principle of air pressure difference method. When the tested sample is cultured at a constant temperature of 20 ± 1 ℃ for five days, it undergoes biological oxidation to convert organic matter into nitrogen, carbon, and sulfur oxides, and produces carbon dioxide gas that is absorbed by sodium hydroxide. The pressure inside the culture bottle decreases, and the change is converted into an electrical signal through a pressure sensor, thereby detecting the BOD of the tested sample₅The value.

Widely used in environmental protection, water quality monitoring, agriculture, forestry, soil, teaching and research departments.
