Laser Methane® mini Gen2


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 safe distance.


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.


Safety First


• Remote measurement and detection, up to 100 metres


• No specialist or special access equipment required to detect leaks


• ATEX approved for industrial use and now includes mining applications


Easy to Use


• Portable – truly hand-held


• Light weight, compact and robust design


• Intuitive menu


• Full colour numeric or graphical display


Flexible and Convenient


• User programmable alarm and offset levels


• Long battery life – allowing 6 hours of continuous operation from one battery


• Self-check and self-calibration at start-up, saves time and ensures consistent high performance and reliability


Accuracy and Reliability


• Responds specifically to methane


• Exceptional accuracy – detect seven very low levels of methane


• Fast response time, typically 0.1 second


Laser Methane® mini Gen2


Crowcon’s Laser Methane® 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 in seconds.


Measurement Principle


By pointing the Laser Methane® 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, aserMethane® 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.


Typical Applications


• Methane beyond reach i.e. difficult to reach or inaccessible areas


• Large area monitoring e.g. pipeline survey


• Hazardous area monitoring eg petrochemical refinery


• Secondary disaster prevention i.e. accumulated gas clouds in roof spaces of buildings in commercial and industrial property


• Methane detection through windows/letterbox of unoccupied property
