This long-range laser remote methane detector adopts Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology to rapidly and accurately locate methane gas leaks within 0.5–200 m. Field operators can perform safety-side inspection on hard-to-access or unreachable areas, including busy roadways, overhead pipelines, external high-rise risers, long-distance transmission pipelines and unattended indoor compartments. The equipment greatly boosts the efficiency and coverage of routine pipeline patrols, enabling leak inspection for previously inaccessible zones.
· Long-distance detection: Detect methane and methane-mixed gas leaks from 0.5–200 m away
· Ultra-fast response: Response time ≤ 50 ms
· High measurement specificity: Laser spectrum only reacts to methane, free from interference of ambient environmental factors
· Long continuous runtime: Minimum 12 hours of battery life
· Low operational threshold: Automatic self-test on power-on; no regular calibration required, nearly maintenance-free
· Ergonomic handheld structure for easy portability
· Intuitive human-machine interface optimized for field patrol operations
· Reliable micro-leak identification even under strong wind conditions
