Crowcon Detection Instruments' second generation, ATEX-approved LaserMethane mini Gen2 (LMm) portable methane detector detects methane at distances to 20m in seconds.

By pointing the laser beam towards a suspected leak or survey line, such as a gas pipe or ceiling, methane concentration is measured by detecting the difference between light emitted and light received.

The device uses a laser diode tuned 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 operation and calibration of the laser diode by referencing an inbuilt methane cell. This ensures accuracy and reliability.

ATEX approval allows the LMm to be used in Zone 1 hazardous areas for on-plant use, in M2 mining applications, and to detect escapes in hard-to-reach or inaccessible areas.
