Overview
NA-SKX212 sensor is polarographic type residual chlorine water quality detection sensor. The remaining chlorine molecules in the solution to be measured reach the cathode surface of the electrode through the selective film of the sensor. Under the polarization of the cathode, the remaining chlorine molecules are reduced due to gets electrons and the anode are oxidized due to lose the electrons. At the same time, a current signal is generated, and the signal size is proportional to the concentration of residual chlorine. The concentration of residual chlorine can be determined by detecting the current signal magnitude in the electrode reaction process.
Key Features
Low power consumption, high precision, linear output, analog signal output.
Applications
It is widely used in the monitoring of residual chlorine content in water works, medical wastewater treatment and swimming pools.
