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

In the following chart you can see when the methanol starts to break through the internal filter in the CO sensor. The CO reading does not begin to rise until almost minutes after the methanol exposure is ended. It took several hours for the CO sensor to finish stabilizing back on zero after the exposure to methanol. It should be noted that the final stable reading of 13 ppm for the 2CF CO sensor is extremely low compared to the response of most other CO sensors.
