SPS-Cl Chlorine Water Quality Sensor

The chlorine sensor adopts membrane-covered, amperometric potentiostatic 3-electrode, which effectively improves the sensor’s measurement stability and accuracy. The free chlorine or total chlorine factor enters the sensor through the selective permeability membrane, and a redox reaction occurs on the surface of the gold electrode to generate a weak current. The signal value obtained after processing is proportional to the free chlorine or total chlorine concentration. After calculation, the free or total chlorine concentration can be obtained. SPS-Cl series chlorine sensors are widely used in tap water, pipe networks, medical sewage, and other fields and can provide customers with accurate and efficient monitoring.

Three-electrode coating method, stable and accurate measurement
No chemical reagent consumption, environmentally friendly
Long maintenance-free period and low maintenance cost
