How Do Electrochemical Sensors Work? Gas Monitors and ...

17/03/2021· Gas finds its way into the outlet of the membrane on top of the sensor housing. Once the gas reaches the working electrode, an electrochemical reaction occurs. This reaction is either an oxidation or a reduction, depending on the type of gas. (For example, carbon monoxide gets oxidized into carbon dioxide, and oxygen gets reduced to water). Oxidation causes the flow of electrons to move …
