IRmax Infrared Hydrocarbon Gas Detector by Crowcon

IRmax is a compact, low power and highly rugged infrared (IR) gas detector, that delivers rapid, fail-safe detection of methane, butane, propane and many other hydrocarbon gases and vapours. The IRmax infrared gas detection system offers the choice of a detector only, a local gas/status display, a remote gas/status display or non-intrusive calibration via an I.S. calibration tool or hand-held HART communicator.

Dependability in all conditions is what makes the IRmax stand out from the crowd, with the reliability of the IRmax hydrocarbon detector proven in hot, cold, wet and saline environments.

IRmax's unique Stay-ClIR optical components are treated with a highly durable coating that completely prevents faults due to condensation, making it ideal for offshore use.

Certified for use in Zone 1 & 2 and EMC compliant*, the IRmax is compatible with virtually any control system, requiring minimal routine maintenance helping keep costs at a minimum. The IRmax also contains no components for artificially heating optical surfaces, meaning power consumption is dramatically reduced, requiring only 1W of power.

The remote display can be mounted up to 30 metres from the IRmax and test gas can be applied without requiring direct access to the detector. It can also be wall mounted, fitted to a 50mm (2 inch) pipe or connected to an auxiliary junction box, making it a reliable and versatile choice for hydrocarbon gas detection.
