Portable COD Water Quality Detector

The portable COD water quality detector measures the chemical oxygen demand of water samples through chemical digestion and colorimetry. The instrument features a built-in heating module to accelerate oxidation reactions and uses a photometer to detect the absorbance of the colored solution, which is then converted into COD concentration. It is suitable for on-site rapid detection of organic pollution levels in sewage and industrial wastewater.
Selection
When selecting, focus on ensuring the detection range matches the actual concentration of water samples, and that the digestion temperature and time comply with standard methods. Verify that the instrument's protection rating is suitable for field environments, and consider how the shelf life of supporting reagents and the complexity of operating procedures affect ease of use. Data storage functionality and calibration cycles are also important factors to consider.
