Winsen Electronics, as a professional gas sensor manufacturer, produce formaldehyde sensor, CH2O gas sensor for industrial use.
ME3-CH2O electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.
Detecting CH2O/FORMALDEHYDE in industry and environmental protection field
