How Does an Electrochemical Carbon Monoxide Sensor Work ...

Electrochemical sensors use a gel to detect CO. Electrochemical sensors are mainly used to detect Oxygen and toxic gas. They measure a chemical reaction within the sensor that creates an electrical output proportional to the CO level. Essentially, EC sensors are small fuel cells composed of noble metal electrodes in an electrolyte. AlphaSense is one of the most popular manufacturers of ...

Operating principle ‐Electrochemical-type gas sensor

Figaro Electrochemical-type gas sensor are amperometric fuel cells with two electrodes. The basic components of two electrode gas sensors are a working (sensing) electrode, a counter electrode, and an ion conductor in between them. When toxic gas such as carbon monoxide (CO) comes in contact with the working electrode, oxidation of CO gas will occur on the working electrode through chemical ...

Effect of electrode pores on the performance of CO ...

In a CO electrochemical sensor, the gas must pass through the pores of the electrode after it passes through the upper hole of the sensor housing, where it reacts according toWorking Electrode (1. Therefore, we can briefly assume that the presence of CO gas in the catalytic regions has two stages: first penetration of CO gas through the pores, and second its reaction on the catalytic sites. So ...
