L20 Non-Contact TDLAS Methane Detector for Building & Pipeline Inspection
Product Introduction
The AiLF L20 is a remote methane inspection device designed for city gas networks, building gas leak surveys, and urban infrastructure inspection. Its non-contact laser measurement allows operators to check suspected methane sources from a distance, making it practical for inspection points that are difficult to reach directly.
Building and City Gas Inspection
The L20 is designed for field surveys around buildings, gas pipelines, valves, storage facilities, and other natural gas infrastructure. It helps operators inspect multiple potential leak points efficiently without needing to approach every target closely.
Selectable Inspection Modes
The L20 provides High Sensitivity, Building, Pipeline, and Auto modes, allowing the inspection process to be adapted to different environments and target types. These modes support routine gas surveys, building inspection, and pipeline leak checks.
Targeted Leak Verification
A green dot sight helps operators aim at specific inspection points, while configurable visual and audible alarms provide immediate notification of detected methane signals. The large display provides direct measurement information during field operation.
Digital Inspection Records
Through Bluetooth connectivity and the ADA mobile app, inspection data can be associated with GPS locations, notes, and photos. This helps create structured records for leak surveys, maintenance, and follow-up inspection.
Practical Urban Gas Survey Tool
The combination of remote measurement, selectable inspection modes, and digital record keeping makes the L20 suitable for city gas infrastructure surveys, building inspections, pipeline networks, and other natural gas leak investigation tasks.
