Airflow Resistance Meter

Overview

PMI Airflow Resistance Meter complies with ASTM C522-03 and provides quick and accurate airflow resistivity measurements in Rayls. Air is forced through the material at a specified velocity or flow rate, and the corresponding pressure drop is measured to determine airflow resistivity values.

  • Windows-based software handles all control, measurement, data collection, and report generation; complete manual control also possible
  • Compatible with Windows XP or higher
  • Real-time graphical test display depicts testing status and results throughout operation
  • Non-destructive testing
  • Length of test approximately 10 minutes
  • Minimal maintenance required
  • Multiple sample chambers available
