This is Electrochemical sensor for Ethylene Oxide.(Electrochemical Ethylene Oxide sensor,ETO sensor).
Normal detection range: 0~1 ppm,0~5ppm,0~10ppm,0~100ppm,0~5000ppm
Special detection range can be customized.
The Ethylene Oxide sensor Modules are available too.
Size: ready stock for all 4 series. 7 series are produced according to orders.
SCIENOC's Ethylene Oxide sensor is very stable in normal circumstance for more than 6 months, and can detect Ethylene Oxide 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 ETO sensor can be retrofitted easily to existing product designs.
