Spectrex Quasar Toxic Open Path Gas Detector Series 950

Spectrex, a leading innovator in open path gas detection solutions, offers a state-of-the-art toxic open path gas detection system designed to detect hazardous gases like Hydrogen Sulfide (H2S), Ammonia (NH3), and Sulfur Dioxide (SO2). This advanced detection system provides unparalleled protection by continuously monitoring for gas leaks over impressive distances of up to 60 meters, making it an ideal choice for large-scale industrial applications. Divided into three distinct models, the Spectrex toxic open path gas detection system ensures comprehensive coverage of critical areas and facilitates prompt action in case of potential gas releases.

For each specific gas there is a different model that fits the specific needs. H2S can be detected by the Spectrex Safeye Toxic Quasar 950 open path gas detection series that is divided in to three models.


The three Quasar 950 models, are each designed to cover specific distances according to the requirements of the application:

–  Safeye Quasar 951 Short Range (5 to 16 meters): Ideal for compact industrial spaces or locations requiring precise gas detection within a limited area.

– Safeye Quasar 952 Medium Range (14 to 40 meters): Perfect for mid-sized facilities or areas where a broader coverage is necessary without compromising on detection accuracy.

– Safeye Quasar 953 Long Range (35 to 60 meters): Suited for large industrial complexes or outdoor installations where gas leaks can occur over considerable distances.


Spectrex has been a leader in the Flame and Open Path Gas Detectors field since the early 50’s. Being acquired by Emerson/Rosemount in 2015 They are fully committed to enhance the safety of your employees, capital investments and to the environment.

Being the first to launch major innovations that have become trade standards such as the first UV/IR and patented IR3 Flame Detector designs they continue to offer the most comprehensive product line to meet application challenges from offshore oil & gas to waste handling to commercial mall floors worldwide.

Spectrex was first to incorporate the Xenon Flash in open path gas detectors to solve false alarm issues common in the industry.

Today they offer hydrocarbon, and toxic ammonia, sulphoric acid and hydrogen sulphide open path gas detection solutions.

Spectrex is fully committed to continue its innovative approach and development efforts to address the needs of the high risk – high value industries for reliable and unique solutions that provide effective protection against fires and explosions.
