PMI Airflow Resistance Meter by EQBAY Authorized Dealer – Precision Airflow Resistivity Measurement System

The Porous Materials Inc. Airflow Resistance Meter, available through EQBAY authorised dealer, is a specialized laboratory instrument designed to measure airflow resistance and resistivity of porous and fibrous materials with high precision. The system operates by passing controlled airflow through a sample while accurately measuring the pressure drop across it, enabling direct calculation of airflow resistivity in Rayls. Designed to meet ASTM C522 03 requirements, the instrument is widely used in acoustic material testing, filtration media evaluation, and research applications. It features advanced pressure and flow sensors combined with intuitive software for full control, real time monitoring, and automated reporting. The system provides non destructive testing, fast analysis, and high repeatability, making it ideal for both laboratory and industrial environments. Its flexible configuration allows testing with air or other compatible gases, ensuring adaptability across a wide range of porous materials.
