Features of the new Laser Methane mini

The LMm (Laser Methane mini) is designed to remotely detect methane, as well as other gas mixtures containing methane (natural gas or similar gases). It allows to quickly and safely find the point of gas leakage by pointing the laser beam at the studied area.

  • Bluetooth communication
  • Realtime data display and measuring
  • GPS location tracking
  • Data storage for traceability
  • Ability to capture and store images
  • Email data transfer

Convenient for regular inspections.

The LMm (Laser Methane mini), measurement principle of this equipment uses the characteristics of methane, which absorbs the laser beam (infrared rays) of a specific wavelength (infrared absorption technology). The laser beam directed at targets such as gas piping, the ground, overhead pipe, etc., will reflect back a diffused beam from the target. The device will receive the reflected beam and will measure the absorptivity of the beam, which will then be calculated into methane column density (ppm-m).

LMm BE Mini Laser Methane Detector FAQs

Not yet. The iOS app release is scheduled for 2020.

No, each device is designed to detect a specific gas. This provides a 100% probability of leak detection of methane and not any other gas.

Laser radiation is completely safe, it corresponds to class 1.

Yes, the instrument works in all weather conditions.

No, there is no impact.

No. The detector contains a reference container with methane inside and calibration is performed at each start-up and during operation.

It works remotely. There is no direct contact with the hazardous environment.

No, since this device modification does not provide for recording or transfer of inspection data. The quadcopter version also has an increased detection range.
