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

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%. (Not GfG sensors, of course!) Sometimes the cross ...

How Gas Detectors Work - Thomasnet

· As detectors measure a specified gas concentration, the sensor response serves as the reference point or scale. When the sensor's response surpasses a certain pre-set level, an alarm will activate to warn the user. There are various types of detectors available and the majority serve the same function: to monitor and warn of a dangerous gas level. However, when considering what type of ...
