Basic Information

Detailed Description	The sensor is a polarographic residual chlorine water quality detection sensor. Residual chlorine molecules in the test solution pass through the sensor's selective membrane to the cathode surface of the electrode. Under polarization at the cathode potential, the residual chlorine molecules gain electrons and are reduced, while the anode loses electrons and is oxidized. This generates a current signal, the magnitude of which is proportional to the residual chlorine concentration. The concentration of residual chlorine is determined by detecting the magnitude of the current signal during the electrode reaction.
