Residual Chlorine

Online sensors-Residual Chlorine

Online residual chlorine sensors monitor the concentration of residual chlorine and hypochlorous acid (HOCl) in water to ensure continuous disinfection. They are widely used in drinking water, industrial water treatment, and membrane process influent monitoring such as reverse osmosis. The sensors use membrane or constant voltage methods, feature high accuracy, fast response, multiple installation options, and IP68 protection...

Product Introduction：

Residual chlorine refers to the amount of chlorine remaining in water after chlorination disinfection. It is used to inhibit the re-proliferation of residual microorganisms in water and ensure continuous bactericidal ability.

Product Application：

On-line monitoring of hypochlorous acid (HOCL) and residual chlorine concentration in drinking water and industrial process water disinfection processes, as well as monitoring of residual chlorine in the influent of membrane treatment processes such as reverse osmosis.
