411 Hydrogen Sulphide Duct Mounting Open Path Detector (2-8 M), UV Flash by Crowcon

Open Path IR or "line of sight" optical gas detectors offer reliable detection of hydrocarbon gas emmissions over large areas. OPIR detectors detect gas hazards ranging from low level Parts Per Million (PPM) levels to Lower Exposure Limit (LEL) levels in hazardous areas.

Features:

  • Hydrocarbon and H2S versions available
  • Explosion proof to ATEX, UL and GOST-R Standards
  • Choice of models for ranges of 0.6m up to 140m
  • Aluminium or stainless steel construction
  • 4-20mA or RS-485 operation, with alarm and fault relays available

GENERAL SPECIFICATIONS

Detected Gases Detection of toxic gases such as hydrogen sulfide (H2S), Ammonia (NH3) and aromatic hydrocarbons such as Benzene, Toluene, Xylene, Styrene, etc.
