Airflow Resistance Meter
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.

| Pressurizing Gas | Clean, dry compressed air or other non-flammable, non-corrosive gases. |
| Pore Pressure | 250 psi or higher |
| Pressure Transducer Range | 0 to 500 Pa |
| Resolution | 1 part in 60,000 |
| Accuracy | ±0.15% of full scale |
| Mass Flow Transducer Range | 10 cm³/min to 500,000 cm³/min |
| Power Requirements | 110/220 VAC, 50/60 Hz (other options available) |
| Dimensions | 30 in (H) × 19 in (W) × 18.5 in (D) |
