Pistol-Style Laser Methane Detector
Product model: LYY150


Product model: LYY150















LYY150 is a pistol-style handheld laser methane detector in the 150 m configuration. It uses tunable diode laser absorption spectroscopy (TDLAS) to detect methane along the laser path, supporting remote inspection of suspected leaks. Typical field tasks include gas-network inspections, valve and regulator checks, and surveys of elevated or difficult-to-access pipework.
The transmitter and receiver share a probe. The laser is aimed at a surface beyond the inspection area, and the receiver measures the returned light. Methane in the optical path absorbs part of the laser signal. The instrument calculates a path-integrated methane reading, displayed in ppm·m.

Switch on the detector, aim the laser at a surface beyond the suspected leak area, and scan the inspection path while observing the methane reading. Use the green aiming laser and scope to position the beam, and monitor the display and sound alarm during inspection.
Tell our sales representative your required inspection distance, preferred instrument style and inspection environment to discuss the appropriate model.
