National gas is composed of more than 75% methane. There is a high demand for an easy and cost-efficient method for the detection of methane in all sectors of the natural gas industry. From production through processing and transmission, to distribution; an impressive number of applications can be realized with the LMC sensor including line, tank and asset inspections, landfill emission monitoring, and surveys in difficult to access areas that previously required scaffolding. The booming LNG and the shale gas industries are other markets with huge opportunities for leak detection services.
The LMm (Laser Methane mini) is designed to remotely detect methane, as well as other gas mixtures containing methane (natural gas or similar gases). It allows to quickly and safely find the point of gas leakage by pointing the laser beam at the studied area.
LMm Advantages - Convenient for regular inspections.

The measurement principle of this equipment uses the characteristics of methane, which absorbs the laser beam (infrared rays) of a specific wavelength (infrared absorption technology). The laser beam directed at targets such as gas piping, the ground, overhead pipe, etc., will reflect back a diffused beam from the target. The device will receive the reflected beam and will measure the absorptivity of the beam, which will then be calculated into methane column density (ppm-m).
