COD water quality automatic monitor

The COD water quality automatic monitor decomposes organic matter in water samples through chemical oxidants, and uses photometric or electrochemical methods to measure the amount of oxidant consumed, which is then converted into a COD value. It is used for real-time monitoring of the degree of organic pollution in water bodies and is commonly found in scenarios such as discharge outlets of sewage treatment plants and river cross-sections.
Selection
When selecting, consider the measurement range to match the COD concentration of the water body, using national standard methods such as the potassium dichromate method. Pay attention to the ability to resist chloride ion interference, maintenance cycles, and reagent consumption costs. It must have data storage and transmission functions, and the protection rating should be suitable for the installation environment.
