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.

Feature:

Small size ,High selectivity ,High accuracy ,Linear output ,Long life

Application:

Residential and commercial detectors ,Houseboat and moto home ,Air purifier ,Ventilation control ,Smart home
