Description

414 Hydrogen Sulphide Open Path Detector (30-100 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
