LEL Gas Detectors

LEL, or lower explosive limit, is an important term when working with calibration gases. It is the lowest concentration of a gas or vapor in air that is capable of producing a flash of fire when exposed to an ignition source. LEL Gas Detectors are easy to use and monitor different types of gas to maintain a safe ratio of combustible gas. LEL Gas Detectors come in fixed and portable varieties.
