This is Electrochemical sensor for Nitrogen Dioxide (Electrochemical Nitrogen Dioxide sensor,NO2 sensor).
Normal detection range:0~0.175ppm,0~1ppm,0~10ppm,0~20ppm,0~200ppm,
0~250ppm,0~300ppm,0~500ppm,0~5000ppm,0~10000ppm.
Special detection range can be customized.
The Nitrogen Dioxide sensor Modules are available too.
Size: ready stock for all 4 series. 7 series are produced according to orders.
SCIENOC's Nitrogen Dioxide sensor is very stable in normal circumstance for more than 6 months, and can detect Nitrogen Dioxide 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 NO2 sensor can be retrofitted easily to existing product designs.
