This is Electrochemical sensor for Hydrogen arsenide.(Electrochemical Hydrogen arsenide sensor).
Normal detection range: 0~1 ppm,0~2ppm,0~3ppm,0~10 ppm,0~20 ppm,0~50 ppm,0~100 ppm,0~1000ppm
Special detection range can be customized.
The Hydrogen arsenide sensor Modules are available too.
Size: ready stock for all 4 series. 7 series are produced according to orders.
SCIENOC's Hydrogen arsenide sensor is very stable in normal circumstance for more than 6 months, and can detect Hydrogen arsenide 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 Hydrogen arsenide sensor can be retrofitted easily to existing product designs.
