Pergam - Model LMm -Portable Methane Detector

Principle of measurement

The LaserMethane mini (LMm) is an portable detector that allows methane gas to be detected from a distance. 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 refl ected 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).

Difficult to reach areas

Accumulated gas clouds in commercial and industrial facilities are commonplace. The Laser Methane mini allows for detection removing the need for ladders, scaff olding or aerial platforms.

Current methods such as FID, require users to Ье within arm`s reach of а poten­tial methane source, and to position the detector into the gas cloud, often requi­ring scaffolding or special access equip­ment to reach the area of interest. ln stark contrast, the Laser Methane handhelds only need the emitted beam to pass through the gas cloud in order to detect methane. Ву simply pointing the laser beam towards а suspected leak, or along а survey line the handheld detector will monitor the level if methane is detected.

There are two versions of LMm:

1. LMm BE (SA3C32A-BE) with Bluetooth
2. LMm NE (SA3C32A-NE) without Bluetooth
