The second generation LaserMethane mini Gen2 from Crowcon is changing the way methane can be detected. Using laser technology, LaserMethane mini Gen2 (LMm) allows users to reliably and accurately detect methane, at a safe distance. They can get results in seconds by simply pointing the laser beam towards the suspected source. The concentration of methane is measured by detecting the difference between the light emitted and the light received.

In order to achieve high detection sensitivity and selectivity for methane, LaserMethane mini Gen2 uses a wavelength that both exhibits maximum adsorption and is unique to methane. The methane column density is the concentration of methane between the detector and the target and is the product of the concentration of the methane cloud (ppm.m) and path length through the cloud (metres) and is reported in units of ppm.m.
