Product Description:

ME4-CO-E4 carbon monoxide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with carbon monoxide and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of carbon monoxide. So the concentration of the target gas could be got by measuring the value of current. The 4th electrode (auxiliary electrode) is used to compensate the zero current, to make it has the characteristics of strong signal level and low zero current.
