Detection without heated mirrors

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

Unlike conventional IR gas detectors, IRmax does not use heaters to prevent condensation on windows and mirrors. Instead, its optical components are treated with a highly durable hydrophobic coating called STAYCLIR which is said to prevent signal faults due to condensation.

As IRmax contains no components for artificially heating optical surfaces, power consumption is reduced. It requires less than 1W of power, typically 75-90% lower than some conventional IR gas detectors.
