What is the purpose of a Combustible Gas Detector (CGD)?

The purpose of a Combustible Gas Detector (CGD) is specifically designed to detect the presence of combustible gases, which allows for the identification of potential gas leaks in residential or commercial settings. These devices are equipped with sensors that react to specific gas compounds, alerting users to unsafe conditions before they can lead to hazardous situations such as explosions or fires.

Using a CGD helps to improve safety by providing early warnings, enabling timely action to rectify leaks or ventilate affected areas. Detecting the location of gas leaks can ultimately save lives, reduce property damage, and ensure compliance with safety regulations.

The other options do not align with the primary function of a CGD. Measuring air pressure pertains to pressure gauges, assessing combustion efficiency connects to combustion analysis tools, and monitoring humidity levels relates to hygrometers. Each of these tools serves distinct purposes that are not related to the detection of combustible gases.
