IR hydrocarbon detector

Crowcon's new IRmax is an ultra-compact infrared (IR) gas detector which delivers rapid, fail-safe detection of hydrocarbon gases with very low power consumption. Far smaller and lighter than comparable IR detectors, the IRmax is easy to install in even the most inaccessible locations, says Crowcon.

Featuring dual-wavelength IR sensor technology in a rugged 316 stainless steel package, IRmax is designed to operate in the harshest conditions in temperatures ranging from -40 to +75°C.

Unlike conventional IR gas detectors, IRmax does not utilise heaters to prevent condensation on windows and mirrors - instead it has STAY-CLIR optical components, which are treated with a highly durable coating that prevents faults due to condensation.

Because IRmax contains no components for artificially heating optical surfaces, power consumption is dramatically reduced - the device requires only 1 Watt of power, 75-90% lower than conventional IR gas detectors.

IRmax detectors require smaller and lower cost power supplies and battery back-up systems. In addition, low power consumption also means longer cables can be used and more detectors can be powered on addressable networks.
