S01088 86ASU Air Sampling Unit - for TXgard-IS by Crowcon

The Air Sampling Unit (ASU) is designed to be used with Crowcon’s Xgard range of detectors for monitoring potentially hazardous gases within ventilation ducts.


  • Enables air ducts to be monitored without requiring the detector to be mounted within the duct.
  • Avoid sensor drift due to air-flow effects.
  • Simple, easy to install design.
  • Simple detector maintenance: there is no need to access the duct for calibration purposes.
  • Extremely reliable; ASU has no moving parts.
