LEL Gas Detector (Combustible)

Wired combustible gas detectors continuously monitor gas concentration as %LEL and trigger alarms or shut-off valves before explosive levels are reached.

They are commonly used in commercial kitchens, gas rooms, boiler spaces, and filling stations, often integrated with fire panels and solenoid shutoffs.

Proper placement depends on gas density (low for LPG, high for methane) to ensure early warning.
