Study Notes

Handheld Laser Methane Detectors

  • Handheld laser methane detectors are gas pipeline inspection tools using laser technology for non-contact measurement.
  • Devices can remotely measure and locate leaks.
  • Improved efficiency and reduced labor compared to traditional methods.
  • Detection range: 0-50m, 0-100m, and 0-150m (depending on model)
  • Continuous operation: up to 8 hours.

Features

  • Compact and lightweight design for ease of use.
  • Selective for Methane gas.
  • 5ppm sensitivity.
  • Rapid response, minimizing alarm delay.
  • Measurable units include PPM, LEL, and VOL.
  • Improved visibility through spotter beam.
  • Self-testing function and low voltage alerts.
  • Low power consumption.

Applications

  • Used for detecting methane gas leaks in gas pipelines, oil refineries, chemical plants, and other related industries.
  • Ideal for inspecting pipelines under roads, near green belts, and alleys.
