Long-Range Laser Remote Methane Detector

Long-Range Laser Remote Methane Detector

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.

Features

· 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
