Methane Detection at a Distance
The second generation LaserMethane mini Gen2 from
Crowcon is changing the way methane leaks can be detected.
Utilising laser technology, LaserMethane mini Gen2 (LMm)
allows users to reliably and accurately detect methane, at a
Get results in seconds by simply pointing the laser beam
towards the suspected leak, or along the survey line. This
removes the need to access fenced-off, high level or other hard
to reach areas.
Remote measurement and detection, up to 100
No specialist or special access equipment required
to detect leaks

Crowcon’s LaserMethane mini Gen2 can accurately and
reliably detect gas leaks from a distance. What was once a
time and resource consuming activity can now be completed
Measurement Principle - By pointing the LaserMethane mini Gen2 at a suspected
leak or survey area, such as a gas pipe or ceiling, 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.
