of such electrochemical sensors. The physical size, geometry, selection of various components, and the construction of an electrochemi-cal sensor usually depends on its intended use. Quite often, the final design results in a compromise between various performance parameters of the electrochemi-cal sensor. The most common misconception about electrochemical sensors is that they are all the same.

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 ...
