ULD200 Handheld Laser Methane Detector employs cutting-edge TDLAS technology, enabling non-contact, remote detection in areas that are difficult for inspectors to access. This device accurately and swiftly locates leakage points and sources, enhancing work efficiency and reducing labor demands.
The TDLAS sensor offers high sensitivity, rapid response, and exceptional selectivity, responding exclusively to methane and minimizing the risk of false alarms from other hydrocarbons. It is widely used in municipal gas pipelines, oil refineries, chemical plants, and other industries where gas leaks are a concern, including petroleum, petrochemical, metallurgical, and power sectors.
Features:
Detects methane leaks up to 50 meters away.
Compact, lightweight, and easy to carry.
Detects methane at 5 ppm·m with no alarm delay.
One-button operation with a color LCD display.
Visual, audible, and vibration alerts with adjustable levels.
Shockproof, low power consumption, and intrinsically safe design.
