COD online water quality analyzer

The COD online water quality analyzer measures the organic matter content in water samples through the chemical oxidation method. It uses oxidants such as potassium dichromate or potassium permanganate to decompose organic matter under heating conditions, and calculates the COD value by detecting the consumption of the oxidant. It is used for real-time water quality monitoring at sewage treatment plants and industrial enterprise discharge outlets, enabling continuous automatic sampling and analysis.
Selection
When selecting, consider that the measurement range covers the actual water quality concentration, use corrosion-resistant materials to adapt to the on-site environment, ensure that the maintenance cycle and consumable costs align with operational capabilities, ensure that the data output interface is compatible with the existing system, and include automatic cleaning and fault diagnosis functions, with reference to operational cases of similar water quality.
