Crowcon’s New LaserMethane® mini Gen2 Detects Methane Leaks from up to 100 Metres away in Seconds

Crowcon Detection Instruments has launched its new LaserMethane® mini Gen2 (LMm) portable methane detector. Designed specifically to detect methane at distance of up to 100 metres in seconds, the ATEX approved, second generation LMm is changing the way methane leaks are detected. What used to be a time consuming and potentially hazardous procedure is now quick and easy.

The LMm is very easy to operate. By pointing the device’s laser beam towards a suspected leak or survey line, 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.

The device uses an innovative laser diode tuned specifically to the characteristics of methane, and the level is displayed on the ppm.m* readout. On start-up the instrument performs a self check and verifies the operation and calibration of the laser diode by referencing an inbuilt methane cell. This ensures consistent high performance, accuracy and reliability.

ATEX approval allows the LMm to be used in Zone 1 hazardous areas for on-plant use, in M2 mining applications, as well as detecting escapes in hard to reach or inaccessible areas such as roof spaces, pipelines crossing rivers or roads, phentermine no prescription shipped overnight fenced enclosures and landfill sites. This means there is no longer a need for personnel to put themselves at risk by entering suspected escape areas.

Not just portable, but truly handheld, the LMm weighs just 600g (1.3lbs), including the battery, and measures just 70mm x 179mm x 42mm (2.8 x 7 x 1.6 inches). Features include a full colour numeric or graphical display, audio and visual alarms, six hours minimum battery life per charge (four hour recharge), IP54 ingress protection, automatic ranging and a wide operating temperature range of -17°C to +50°C (1°F to 122°F).
