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
