L20P 200m / L20 150m Remote TDLAS Methane Leak Detector for Pipelines

Fast-Response Remote Laser Methane Leak Detector

The AiLF Instruments L20P and L20 are handheld remote methane leak detectors designed for fast, non-contact inspection of natural gas pipelines and industrial facilities. Using TDLAS laser absorption technology, they detect methane concentrations from a distance without requiring direct contact with the suspected leak source.

The L20P provides a maximum detection distance of 200 m, while the L20 offers a detection distance of up to 150 m. With a measurement range of 0–100,000 ppm·m and a stated response time as fast as 0.05 seconds, the detectors support efficient screening of hard-to-reach locations.

Key Features

• Long-Range Detection: Up to 200 m for the L20P and 150 m for the L20.

• Rapid Response: Supports fast identification of changing methane signals.

• Precision Targeting: Optional sighting scope supports long-distance aiming and leak localization.

• TDLAS Technology: Selective laser absorption measurement for non-contact methane detection.

• IP68 Protection: Designed for demanding inspection environments.

• ADA Mobile App: Records gas readings alongside timestamps, GPS coordinates, notes and photos.

• Inspection Traceability: Exportable inspection records support documentation, reporting and follow-up maintenance.

Applications

• Natural Gas Pipelines: Remote inspection of pipelines, valves, joints and other potential leak locations.

• Oil and Gas Facilities: Methane leak screening around wellheads, storage facilities and processing equipment.

• Industrial Sites: Non-contact inspection of areas that are difficult to access directly.

• Environmental Monitoring: Methane surveys around landfills and natural gas infrastructure.
