ME2-CH2O Type electrochemical formaldehyde gas sensorAccording to the principle of electrochemical work, the use of gas to be measured in the electrolytic cell workThe electrochemical oxidation process of the electrode, through the electronic circuit of the electrolytic cell working electrode and the reference electrode constant in aAn appropriate potential, at this potential can occur under the electrochemical oxidation of the gas to be measured, due to oxygen in the oxidation and alsoThe Faraday current produced by the original reaction is small and negligible, so that the gas electrochemical reactionThe resulting current is proportional to its concentration and follows Faraday\`s law. In this way, by measuring the size of the current can beTo determine the concentration of the gas to be measured.
