How does a gas detector work? | Martek Marine

· The sensor will monitor these currents and alarm the user when the presence of gas approaches an amount that is hazardous. Early instruments were made to detect just one gas but now they can measure several at once – most commonly, oxygen (O2), flammable gases or vapours (LEL), hydrogen sulphide (H2S) and carbon monoxide (CO).

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.
