- Model Mini (LMm) - Innovative Long-range Portable Detector



The LaserMethane mini (LMm) is an innovative portable detector that allows methane gas to be detected from a distance. This enables easy access to hard-to-reach locations, such as elevated piping or locked premises, and helps keep the operator away from potential leak sources. NEW! LMm is now available with a green laser guide light which is more visible especially under strong sunlight. The Laser Methane Mini-Green (LMm-G) combines the benefit of LMm with additional data storage functions and comes with Bluetooth capability, which can be connected to any android device (through the Gasviewer app) for a variety of data storage functions. Important data like location, gas levels and time can also be saved or emailed to a central point. Features include: - Wide organic electroluminescence display - Detection from up to 30m away in standard mode, 100m with a reflector - Compact and lightweight - Data storage - No moving parts so little maintenance required.

Utilising Tuneable Diode Laser Absorption Spectroscopy (TDLAS) methane density is measured and displayed on a clear backlit display in both numerical and graphical formats. In the latest LMm Gen 2 model, this is enhanced with a seperate LED alarm indicator and louder audible notification.

Features include:

  • ATEX approval
  • Detection from up to 30m away in standard mode, 100m with a reflector
  • Compact and lightweight - only 600g
  • 5 hour battery
  • Automatic ranging

The LaserMethane mini performs a self check on start-up verifying the operation and calibration of the laser diode by referencing an inbuilt methane cell. This innovation means accuracy is maintained on the LMm while the need for external calibration is eliminated, maximising up-time and reducing ownership and maintenance costs.
