IRmax is an ultra-compact infrared (IR) gas detector that delivers rapid, fail-safe detection of hydrocarbon gases and vapours. The IRmax 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.
The reliability of IRmax has been proven in hot, cold, wet and saline environments, making it ideal for offshore.
IRmax's unique Stay Clir optical components are treated with a highly durable coating that completely prevents faults due to condensation. As IRmax contains no components for artificially heating optical surfaces, power consumption is dramatically reduced, requiring only 1W of power.
