This is Electrochemical sensor for Chlorine (Electrochemical Chlorine sensor,CL2 sensor).
Normal detection range:0~0.05 ppm,0~1 ppm,0~2 ppm,0~10 ppm,0~20 ppm,0~50 ppm,0~100 ppm,0~200 ppm,0~1000 ppm .
Special detection range can be customized.
The Chlorine sensor Modules are available too.
Size: ready stock for all 4 series. 7 series are produced according to orders.
SCIENOC's CL2 sensor is very stable in normal circumstance for more than 6 months, and can detect Chlorine with excellent accuracy and fast response speed without reduction of sensitivity.standard warranty is 18 months from dispatch time.extended warranty sensors can be customized.
SCIENOC's Electrochemical Chlorine sensor can be retrofitted easily to existing product designs.
