Working principle

Electrolyte and osmotic membrane separates the electrolytic cell and water samples, permeable membranes can selectively to ClO- penetration; between the two electrode has a fixed potential difference, current intensity generated can be converted into residual chlorine concentration.

At the cathode: ClO^- + 2H+ + 2e^-  → Cl^-+ H₂O

At the anode: Cl^- + Ag → AgCl + e^- 

Because in a certain temperature and pH conditions, HOCl, ClO- and residual chlorine between fixed conversion relationship, in this way can measure the residual chlorine.
