Compact and Portable Methane Gas Detector
A new era in portable methane detection has arrived. Truly portable offers the laser methane detector (LMD) and Laser Methane Mini-G (LMmG) users the ability to detect methane in the distance. What was once a time-consuming process is now done in a fraction of the time by using the best diode laser technology.
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 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:
- LMm BE (SA3C32A-BE) with Bluetooth
- LMm NE (SA3C32A-NE) without Bluetooth
