150m Non-Contact Laser Methane Leak Detection
The L20 Remote Laser Methane Leak Detector is a handheld device designed for fast, non-contact detection of natural gas and methane leaks from a distance of up to 150 meters.
Using TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, the detector measures methane through its characteristic laser absorption response, enabling remote inspection without direct contact with the suspected leak source.
With a 0.1-second response time, the L20 is designed to help inspection personnel quickly identify potential methane leaks in buildings, pipelines and hard-to-reach areas.
Smart Inspection & Data Management
The L20 supports Bluetooth connection with a mobile application, allowing users to record GPS-linked readings, inspection notes and photos for easier reporting and traceability.
Four scanning modes—High Sensitivity, Building, Pipeline and Auto—support different inspection scenarios.
A green dot sight helps operators accurately target detection areas in daylight.
Key Benefits
Applications
City Gas & Pipeline Inspection
For remote inspection of natural gas transmission and distribution pipelines, valves, joints and related infrastructure.
Building Inspection
Suitable for checking suspected gas leaks around buildings and other areas that are difficult or inconvenient to access directly.
Oil & Gas
For leak screening around pipelines, wellheads, processing equipment and storage facilities.
Industrial & Environmental Monitoring
Applicable to industrial gas inspections, landfill methane monitoring and natural gas emission surveys.
