Sigma-Static Air Resistance Measurement Systems
SIGMA is used to measure the airflow resistivity and permeability of permeable materials. It is distributed with the SIGMA-X software that fully controls the measurements. It automatically detects the appropriate range of airflow speeds and measures pressure drops in the function of airflow speed to accurately compute the static airflow resistance, the static airflow resistivity, and the permeability. The system is based on the direct method described in ASTM C522-03 and ISO 9053-91 standards.
