Unique Feature of the Laser Methane mini (LMm)

Remote Methane Detection
Truly portable and handheld, the Laser Methane mini (Lmm) offer users the ability to detect methane remotely. What once was time consuming and a resource draining procedure can now be completed in a fraction of the time. This is accomplished by utilizing the best in Tunable Diode Laser Absorption Spectroscopy (TDLAS).

Older methods such as FID require users to be within arm's reach of the potential methane source, and to position the detector into the gas cloud. This often required scaffolding or special access equipment to reach these areas of interest. In stark contrast, the LMn handheld only needs the emitted beam of light (Laser) to pass through the gas cloud in order to detect methane. This can be done by simply pointing the laser beam towards a suspected leak, or along a survey line and the Lmm will monitor the level if methane is detected.

Using the phone application users can generate GPS reports in realtime.

Principle of Measurement

Laser Methane is based on utilization of laser absorption spectrophotometer of methane gas for gas measurement. The system detects natural gas leaks by emitting a laser at particular wavelengths and analyzing the light reflected back from the ground to determine how much was absorbed by the methane in the natural gas. The measured gas volume is expressed by the methane column density (ppm-m): methane density (ppm) multiplied by the thickness (m).

Generate Reports with GPS Data (using phone application)

Using the Android phone application users can easily walk out a line or remotely monitor valves, meters, etc. and the application will record results in realtime, creating GPS mapping data of survey and indicate along the way when/where alarm levels of methane are recorded. This data can be used to verify surveys (date/time/GPS) and identify areas of concern for immediate investigation and resolution. Never has creating accurate reporting been so easy.
