MIX8020N CH2O Electrochemical Formaldehyde Sensor Gas 5ppm

MIX8020N Electrochemical Formaldehyde Sensor/CH2O sensor

Principle Introduction:


MIX8020N Formaldehyde /CH2O gas sensor is a battery operable electrochemical formaldehyde sensor developed by Mixsen. Formaldehyde and oxygen on the working electrode and counter electrode are subjected to oxidation-reduction reaction correspondingly. This produces the electric current. The current is directly proportional to the concentration of formaldehyde and following the Faraday’s law. Through measure the current to get the concentration of formaldehyde.
