Product Overview
LYY100 is a pistol-style handheld laser methane detector in the 100 m configuration. It uses tunable diode laser absorption spectroscopy (TDLAS) to detect methane along the laser path, supporting remote inspection of suspected leaks.
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.
Key Features
- Typical response time of 0.015 s, with a specified maximum of 0.03 s.
- Built-in reference gas cell monitors the laser wavelength for self-calibration.
- Narrowband optical filtering helps reduce sunlight interference.
- Automatic optical-signal adjustment accommodates changes in reflected light strength.
- PC+ABS housing with a matte finish; approximately 650 g.
- Touchscreen operation, sound and LCD alarms, and a green aiming laser with a scope.
- Two user-replaceable batteries with a specified capacity of 8000 mAh.
Applications
- Methane and methane-containing gas leak inspections around gas stations, distribution networks and pressure-regulation facilities.
- Checks around valve pits, process areas, chemical and refining facilities, and overhead pipework.
