Pergam LMs Methane Detector

The Laser Methane Smart (LMs) is the newest of the handheld laser detectors available today. The LMs offers fast and safe remote detection of methane leaks at a distance of up to 30 meters or 100 feet. LMs allows users the convenance of simply aiming the instrument and shoot an inspection point with measured value and even automatically output its data to a cloud server.

Use cases:

Gas Distribution
Underground Gas Storage and Distribution
Above ground Gas Storage and Distribution
Gas Processing Plant
Gas Compression Station

The LMs offers:

Reliability - No moving parts and no gas suction in principle require little maintenance. Self-check and automatic calibration on start-up - ensures accurate and reliable gas leak detection.

Remote detection - Searching range 30m (100ft) keeps operators away from harm. Green guide laser light gives clear visibility of the searching point even under bright sunshine.

Persuasive evidence - Laser co-axis digital camera records photos of inspection points. Storing data on a cloud server secures measurement data and the photos via android or iOS devices.

User-friendly - Point and shoot technology requires little or no training to use. The weight is only 500g (~1 lbs), including batteries.

There are hidden images / Tidy mode active.

LMs Advantages

The LMs offers a broader area of search due to the sweeping of the beam.

Fast Response and Sensitivity - Detects faster than conventional methods (Detection speed: 0.1 seconds)

Detects leaks from a SAFE distance (Point laser beam towards suspected leak or along the pipeline when surveying).

Utilize scanning technique versus a probing technique.

Certified Explosion-Proof (ATEX approval for use in hazardous areas: Zone 1)

No false indications (Reacts only to methane)

No test gas needed - Rapid warm-up, self-calibrating with permanent internal gas reference cell that lasts the unit's life.

Portable and lightweight.

Quickly spot the measuring point - even under bright outdoor sunlight with the green laser pointer's excellent visibility.

Principle of Measurement

Laser Methane utilizes a 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 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).
