The Simtronics GD1 by Teledyne detects H2S gas hazards, suitable for multiple industries from offshore production facilities to wastewater treatment plants.

At the heart of the detector is a tunable laser diode that eliminates environmental effects from sun, rain, sand, and fog. The laser scans single absorption lines where there is no interference from other gases.

Unlike traditional methods for detecting H2S (MOS or EC cell), the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk.

The complete optomechanical design and construction are stable, resulting in ultra-fast response time while providing unparalleled service life and detector stability, thus saving on maintenance and service costs.

The detector is supplied with worldwide hazardous area approvals, is suitable for SIL2 applications and comes with a five-year warranty.

  • First Exd NIR Laser open path detector for H2S safety-related applications
  • Fail-safe with no sleeping affects
  • Separate Transmitter and Receiver concept
  • Non-consumptive technology
  • No cross interference
  • Low detection levels, suitable for personnel safety
  • Operates up to 98% of obscuration, negligible effects from atmospheric changes (fog, etc.)
  • Path length 5 – 75 m
  • Self-test Continuous
  • Covers a larger area of detection removing the need for several point detectors
  • Tx and Rx housing Stainless steel (ASTM 316)
  • Operating Temperature -55°C TO + 65°C
  • Output 4-20mA source or sink & HART
  • Ingress IP66/IP67 according to IEC 60529
  • Approvals ATEX, IECEx, SIL
