Free Chlorine Detector

The free residual chlorine detector employs either the electrode method or colorimetric method to detect the content of hypochlorous acid and hypochlorite in water through chemical reactions. It is used to monitor the disinfection effectiveness of drinking water and swimming pool water, ensuring that water quality meets hygiene standards.
Selection
When selecting, consider the measurement range and accuracy to match the concentration of the water body to be tested. Confirm the calibration method of the instrument and the stability of reagent and consumable supplies. Check that the protection rating is suitable for the operating environment and that the user interface aligns with the skill level of the personnel.
