Chlorine electrode belongs to the Clark type current sensor, manufactured by microelectronic technology, used for measuring water chloric acid (HOCl) concentration time. The sensor consists of a small electrochemical three electrodes, one of which is a working electrode (WE), a counter electrode (CE) and a reference electrode (RE). A method for measuring the concentration of hypochlorite (HOCl) in water is established based on the measurement of the current produced by the change of the concentration of hypochlorite in the working electrode. The working electrode WE separates the electrode surface from the analytical solution by a special layer of organic film. The temperature sensor is integrated into the sensor, which is used for temperature compensation. The measurement conditions of the sensor: the sensor must use chlorine in stirred solution (at the same time, the measuring accuracy is not high) or in the water flow through the pipeline system. If the hydration time is insufficient or energized before contact with the solution, the sensor will be affected.

● Do not use chemical reagents, cost savings;
● Do not need to adjust, maintenance workload less;
● No need to replace electrolyte and membrane, accurate measurement.
