880 digital BOD analyzerIntroduction:

The 880 digital BOD analyzer is designed based on the principle of air pressure difference method. After five days of cultivation under standard conditions, the sample undergoes biochemical reactions 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 cultivation bottle decreases, and the change is converted into an electrical signal through a pressure sensor, thereby detecting the value of BOD5 in the tested sample.

Biochemical oxygen demand BOD5 is a necessary measurement item for water quality evaluation and an important quality indicator for measuring the impact of organic matter on water pollution. The traditional method for determining BOD5 is chemical dilution. This method is cumbersome to operate, requires high experimental skills from analysts, and has a high degree of variability in experimental data, often resulting in inaccurate experimental results.
