Airflow Resistance Meter

The PMI Airflow Resistance Meter follows the specifications of ASTM C522-03 and provides quick and accurate resistivity values in Rayls. Air is forced through the material at required velocity or flow rate and corresponding pressure drop is measured to provide the resistivity valves.
