IR flammable gas detector

IRmax is an ultra-compact infrared (IR) flammable gas detector from Crowcon which delivers rapid, fail-safe detection of hydrocarbon gases and vapours. Featuring dual-wavelength IR sensor technology in a rugged 316 stainless steel package, IRmax is designed to detect methane gas and other potentially explosive hydrocarbons in the harshest conditions.

Unlike conventional IR gas detectors, IRmax does not utilise heaters to prevent condensation on windows and mirrors. Instead, its optical components are treated with a highly durable hydrophobic coating called STAY-CLIR that completely prevents signal faults due to condensation.

As IRmax contains no components for artificially heating optical surfaces, power consumption is dramatically reduced. It requires less than 1 Watt of power, typically 75-90% lower than conventional IR gas detectors. A gas detection system using IRmax detectors therefore requires smaller (and lower cost) power supplies and battery back-up systems. Longer cables can also be used and more detectors can be powered on addressable networks.
