Combustible Gas Detectors
Combustible gas detectors are essential in environments where there's a risk of flammable gas leaks. They are designed to detect the presence of a variety of gases that can burn easily, alerting you to potential fire or explosion hazards.
Combustible gas detectors don't target specific gases but rather a lower explosive limit (LEL). The LEL is the minimum concentration of a gas or vapor in air that will allow combustion to occur in the presence of an ignition source.
Common combustible gases that detectors can identify include:
- Natural gas (methane) - the primary component of natural gas, methane is a highly flammable gas used for heating and cooking.
- Propane - commonly used in liquefied petroleum gas (LPG) tanks for grilling, heating, and industrial applications
- Butane - is a fuel gas found in cigarette lighters and camping stoves.
- Hydrogen - this highly flammable gas is used in various industrial processes and fuel cells.
- Gasoline vapours - fumes from gasoline storage tanks or spills
Additional points to consider:
- LEL settings - some detectors can be adjusted to specific LEL ranges depending on the anticipated gas types in the environment.
- Sensor types - these detectors typically use catalytic bead sensors that react to the presence of combustible gases.
