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

Most substance-specific CO sensors include an internal activated carbon filter designed to remove the H2S and other acid gas interferents before they reach the sensing electrode. Thus, the reading of the sensor is not affected by the presence of H2S in the atmosphere being monitored. While inclusion of a filter is frequently able to increase specificity, removal of a filter may be used to broaden response to a …
