<p>A gas detection apparatus/system, wherein the temperature at the working surface, region, area, or point of the gas sensor (1; 10) provided for detecting the presence of a gas is monitored in addition to the monitoring of the gases to be detected and/or examined whereby the output from the gas sensor is always related to temperature conditions at said working surface, region, area or point. Preferably a temperature sensor (4; 12) is placed at or near this working surface, region, area, or point or is incorporated in the construction of the gas sensor working surface, region, area, or point whereby in either case the temperature thereof can be monitored. If desired, an infrared detector (12) is focussed onto the gas detector working surface, region, area, or point, whereby the temperature thereof can be monitored.</p> |
