PT1E-0930 10.DEFINITION OF WORD The abbreviation LEL stands for Lower Explosive Limit of flammable/combustible gases and vapors. Lower explosive limit This represents the lowest concentration which can be ignited by source of ignition, hence the lowest concentration which can produce and explosion. Calibration By using calibration (standard) gas etc, it seeks for instrument reading, display value or set value and true value.
