Product Overview

LYY50 is a pistol-style handheld laser methane detector in the 50 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.

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.

Operation and Support

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.
