Chlorine Electrochemical Sensor EC-4CL2-50
EC-4CL2-50 is CL2 sensor which detects chlorine in level from 0~50ppm.Since the output current is fairly large, it can detect the low concentration of Cl2 with great accuracy.
Electrochemical Chlorine Sensor EC-4Cl2-50 has very excellent repeatability, long term stability, selectivity and resistivity, it is useful for the concentration control of Cl2 at water sterilization.
The Chlorine(Cl2) Electrochemical Sensor EC-4Cl2-50 can be retrofitted easily to existing product designs.
