For COD it is used to measure the degree of water pollution is an important indicator is beyond reproach, then COD online analyzer is what to do? This chapter water quality online monitoring instrument manufacturers to share the main uses of COD online analyzer! Give a brief introduction to some new users of the instrument.

Cod-8000 –COD online analyzer is reduced to Cr (Ⅲ) in the mixed solution formed by water sample, potassium dichromate, silver sulfate (as a catalyst to oxidize the straight chain aliphatic compounds more fully) and concentrated sulfuric acid under high temperature and high pressure environment, so that the color of the mixture solution changes. The degree of change of the color of the solution corresponds to the solubility of COD (chemical oxygen demand) of the measured water sample. The instrument can directly determine the COD value of the water sample by photoelectric colorimetry. It is one of the water quality monitoring instruments concerned by the environmental protection industry.

With the improvement of people’s living standards, industrial pollution and domestic pollution are becoming more and more serious, and the water environment has also been greatly affected! Like some chemical plants, printing and dyeing plants, paper mills, etc., these are accompanied by a large number of sewage generation, it is because of this, the relevant departments to increase the relevant management, enterprises in the discharge of these sewage must be in the case of compliance, so as to reduce the degree of water pollution. This COD online analyzer is used to detect the content of various substances in the water body, and analyze it to determine whether the water quality meets the discharge standards.
