Crowcon IRmax | ATEX Zone 1 & Zone 2 Hazardous Areas 

Single Gas & Multi-gas Detectors | Fixed Point Gas Detection & Portable Gas Safety Applications | Industrial Locations & Hazardous Area Zones

The Crowcon IRmax fixed gas detector is an infrared (IR) flammable gas detector which is designed is provide a rapid, fail-safe detection of methane, butane, propane and many other hydrocarbon gases and vapours.

IRmax fixed gas detection equipment is compact, low power and reliable even in hot, cold, wet and saline environments making it an ideal fixed gas detector for offshore applications.

The IRmax gas detector offers the choices of a detector only, a local gas/status display, a remote gas/status display or non-intrusive calibration via an intrinsically safe calibration tool or hand-held HART communicator.

IRmax fixed gas detector consume less than 1W of power ensuring compatibility with a wide range of control systems and have a variety of installation options including wall mounted, pipe mounted and connected to an auxiliary junction box.

The IRmax fixed gas detector is also water and dust resistant to IP66.

Crowcon IRmax Bump Testing & Calibration

Routine bump testing is recommended for the range of Crowcon fixed gas detectors prior to each use. Bump testing is a brief application of a gas to the sensor to invoke a prescribed reaction, ensuring the gas detector reacts as expected.

Bump testing provides a quick, easy and direct method of verifying gas detectors are performing as required and takes a lot less time than ‘zeroing’ the device. 

The bump test is widely accepted as a suitable method of testing gas detection equipment. 

The reliability of IRmax has been proven in hot, cold, wet and saline environments, making it ideal for use offshore
