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.
