Quasar 900 Open Path Gas Detectors

RC Systems’ Quasar 900 open path gas detector utilizes the very latest in open path IR technology to detect a wide range of hydrocarbon gases, including alkanes (methane to hexane) and ethylene. These units can be custom-tailored to your high-risk installation.
The Quasar 900 employs “spectral fingerprint” analysis of the atmosphere using the DOAS (differential optical absorption spectroscopy) technique to deliver reliable results in extremely harsh environments where dust, fog, rain, snow, or vibration can cause a high reduction of signal.

Benefits of Open Path Gas Detectors

  • Wider coverage area
  • Most likely method to pick up any leak
  • Very high speed of response
  • No unrevealed failure modes
  • Beam block warning
  • Detector location is less critical
  • Size of gas hazard indicated

Superior Technology & Durable Construction 

Our Quasar 900 open path gas detector provides continuous monitoring for combustible hydrocarbon gases. This device consists of a Xenon Flash infrared transmitter and infrared receiver, which can be separated over a line of sight from 23 ft. (7m) up to 660 ft. (200m).

The Quasar 900 transmitter and receiver are both housed in a rugged, stainless steel, ATEX and IECEx approved enclosure. The main enclosure is EExd flameproof with an integral, segregated, EExe increased safety terminal section.
The hand-held communication unit can be connected in-situ via the intrinsically safe approved data port for prognostic and diagnostic maintenance. The Quasar 900 gas detector is approved to FM/FMC per Class I Div 1 Group B, C and D and Class I, II Div 1 Group E, F and G.

The Quasar 900 includes heated windows to eliminate condensation and icing, HART capability for digital communication, and is designed to meet SIL2 per IEC61508 and FM performance approved per FM6325 and tested per EN60079-29-4.
