Crowcon IRmax is an extremely compact infrared (infrared gas probe) detector that can quickly and safely detect gases and hydrocarbon vapors. The IRmax gas detection system offers the choice of just one gas detection device, a gas status display at the site, a remote gas status display, or non-intrusive calibration through an IS calibration instrument, tool, or HART portable communication connection.

Overview

IRmax’s reliability has been proven in hot, cold, humid, solvent, salt environments, making it ideal for offshore applications.

The special optical composition of IRmax is solved with a high-strength coating that is completely resistant to errors caused by evaporation. Just as IRmax does not include optical surface heating components so the power is significantly reduced, which requires only 1W of energy.

IRMAX FEATURES

Easy to install

  • Compact size – requires less space, effort and time to install.
  • Wide installation option – can be mounted on the wall, positioned in a 50mm pipe or connected to ani assist box using a choice of mounting and installation accessories.
  • 4~20mA industry standard output – compatible with most control systems.
  • HART and RS-485 Modbus connection options

Easy maintenance

  • Non-intrusive remote calibration – IR monitors can be mounted up to 30m from IRmax’s location and gas test can be applied without direct access to the probe.
  • Handheld calibration equipment – IRmax gas detection heads attached to an IS isolation module can be tested and calibration using a portable calibration accessory
  • Stay-Clir optical component avoids vapor adhesion to optical components

Low cost of ownership

  • Low energy consumption – only 1W is consumed, allowing for small power supply and low backup power system.
  • Automatic monitoring of optical component dimming – minimal maintenance keeps prices down
