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 ...
