LEL Lower Explosive Limit: The minimum concentration of a particular gas (or vapor) in air necessary to support combustion. Below the LEL level, the mixture is too lean to burn. Industrial type Combustible or LEL detectors typically provide measurement in the 0-100 %LEL range. The LEL may also be referred to as the LFL or Lower Flammable Limit.
