How Oxygen, Electrochemical Toxic, and ... - Honeywell Safety

The oxidation of carbon monoxide in an electrochemical sensor provides a good example of the detection mechanism: Carbon monoxide is oxidized at the sensing electrode: CO + H2O → CO2 + 2H+ + 2e - The counter electrode acts to balance out the reaction at the sensing electrode by reducing oxygen present in the air to water: 1/2 O2 + 2H+ + 2e- → H 2O Similar reactions allow for the ...

Why is hydrogen such a big issue for CO sensors? | GfG ...

How electrochemical CO sensors detect gas. Gas that enters the sensor undergoes an electrochemical reaction that causes a change in the electrical output of the sensor. The difference in the electrical output is proportional to the amount of gas present. Gas enters the sensor through an external diffusion barrier that is porous to gas but nonporous to liquid. An internal organic vapor filter ...
