Residual Chlorine Concentration Analyzer

Residual chlorine analyzers detect the concentration of free chlorine in water using either the electrode method or the colorimetric method. The electrode method measures changes in electrical potential via a chloride ion-selective electrode to calculate concentration, while the colorimetric method utilizes DPD reagent to react with residual chlorine, producing a color change that is measured for absorbance using a photometer. These analyzers are used for water quality monitoring in applications such as water treatment plants, swimming pools, and food processing, ensuring that disinfection effectiveness meets regulatory standards.
Selection
When selecting, consider a measurement range covering 0-10 mg/L, with an accuracy of ±2% and temperature compensation functionality. Choose the electrode method (for continuous monitoring) or the colorimetric method (for portable detection) based on the usage scenario. Check whether the dustproof and waterproof ratings are suitable for the on-site environment. Confirm the electrode replacement cycle and reagent storage requirements to align with the existing water quality testing process.
