GD1 - Laser Open Path H2S Gas Detector

The GD1 is a cutting-edge solution for detecting gas hazards across diverse industrial settings, ranging from offshore production sites to wastewater treatment facilities. Its core feature is a customizable laser diode, which is unaffected by environmental factors like sunlight, rain, and fog. This laser meticulously scans individual absorption lines, ensuring no interference from other gases.


  • Fail safe
  • Fast response time
  • Calibration free
  • Operates up to 98% of obscuration

 Unlike its counterparts, the GD1 necessitates no recalibration and can seamlessly replace multiple standard detectors, mitigating the same risks. Its optomechanical structure guarantees stability, enabling an incredibly rapid response time while significantly prolonging the detector's life span. This not only enhances operational efficiency but also minimizes maintenance and service expenditures.

Additionally, the GD1 boasts global hazardous area certifications and is ideal for systems demanding SIL 2 compliance.
