- Model RLGD-100 - Remote Methane Laser Detector



The RLGD-100 Remote Laser Methane Detector is an easy-to-operate portable device, capable of detecting methane leads by pointing it towards the survey areas. Utilizing proprietary technology of Tunable Diode Laser Absorption Spectroscopy (TDLAS), the RLGD-100 only detects methane with no cross-interference. This unit also features an OFFSET function to further eliminate the methane in air from affecting detection accuracy. It enables easy access to hard-to-reach locations, and provides protection for operator and industrial applications against a wide range of potential leak sources.

  • Detects methane from a remote distance (Up to 30 Meters)
  • High sensitivity and ultra-fast response down to 0.1 seconds
  • No cross-interferences
  • Self-test and automatic calibration before start-up
  • 8-hour operation time
  • Visual and audible alarms
  • Wireless data logging
