The IR400 Infrared (IR) Point Detector is a hydrocarbon gas detector that continuously monitors combustible gases and vapours within the lower explosive limit (LEL) and provides alarm indication.

It features an industry-leading response time of less than 3 seconds, even with a splash guard installed. All electronics are contained within an explosion-proof housing so that the IR400’s detector information can be processed locally. Configurations with analogue output, Modbus and HART are also available.

Features

  • Multiple communication outputs provide complete status and control capability in the control room.
  • Dirty optics indication discriminates between true fault and cleaning requirements.
  • Fast calibration times reduce the amount of calibration gas required, which lowers maintenance time & costs.
  • Industry-leading speed & response: T90 ≤ 3 seconds, even with a splash guard installed.
