Mecanum’s airflow resistivity meter is designed to obtain a reliable measurement of static airflow resistivity, resistance, specific resistance and permeability for a wide range of open-cell porous materials used for noise control.

This system is based on the direct method described in the ASTM C522-03 and ISO 9053 standards. SIGMA-X software detects automatically minimum flow velocity measurement range and allows you to obtain the pressure drop as a function of the flow velocity as low as 0.5 mm/s.
