L20 Non-Contact TDLAS Methane Detector for Building & Pipeline Inspection
Product Introduction
The AiLF L20 is a long-range non-contact TDLAS methane detector designed for natural gas leak inspection in buildings, pipelines, and other hard-to-access areas. It provides remote methane measurement from up to 150 m, allowing operators to check suspected leak points without direct contact with the target.
Flexible Inspection Modes
The L20 offers four inspection modes: High Sensitivity, Building, Pipeline, and Auto, allowing operators to select the appropriate scanning mode for different inspection tasks. This makes the detector suitable for both building gas surveys and pipeline network inspection.
Precise Targeting and Fast Alerts
A built-in green dot sight helps operators accurately target inspection points, including outdoor operation in daylight. The L20 provides a 0.1 s response time together with configurable visual and audible alarms for fast identification of abnormal methane signals.
Digital Inspection Records
The L20 supports connection to the ADA mobile app via Bluetooth, enabling gas readings to be linked with GPS locations, notes, and photos. This supports structured leak survey records and follow-up inspection management.
Typical Applications
The L20 is designed for natural gas pipeline inspection, city gas network surveys, building gas leak inspection, gas infrastructure maintenance, oil & gas facilities, and environmental methane monitoring.
