The static airflow resistance meter is designed to obtain reliable measurements of the static airflow resistance, resistivity, and static viscous permeability for a wide range of open cell porous materials used in noise control. The system is based on the direct method described in  ASTM C522-03 and ISO 9053 standards.

Measured Properties

1.  Static airflow resistivity (Pa.s/m² or rayls/m)

2.  Static airflow resistance (Pa.s/m or rayls)

3.  Static viscous permeability (m² or Darcy)



Mecanum’s static airflow resistance meter is used by the world’s leading material suppliers for both automotive and aircraft industry for quality control in the manufacturing process of materials; research, development, and innovation, and for feeding acoustical prediction software dealing with sound absorbing materials.



The system includes:

  • Two specimen holders* (100-mm and 44.44-mm diameter) 

        *other sizes are available

  • Thin film holder

  • Certified calibrated resistance

  • Grids to support limp material

  • Rings to minimize airflow leaks around the sample

  • SIGMA-X software

The SIGMA-X software fully controls the measurement and calculates the main properties and statistics related to the measurement. It corrects pressure and temperature. The system works with disc shaped samples.
