The measuring principle of this instrument is that the airflow passes through a specific area of ​​fabric, and the airflow rate can be adjusted according to different fabrics, until the pressure difference between the front and back two fabrics Is the required value. The airflow at this time can be measured, and the air permeability can be calculated based on this. Model: A0002 Air permeability is a system for monitoring the air permeability of textiles, Mainly used in textiles, non-woven fabrics, felts, Fleece, woven, multilayer and other fabrics. The measuring principle of this instrument is that the airflow passes through a specific area Fabric, and this air flow rate can be based on different fabrics And adjust until the pressure difference between the two fabrics Is the required value. The airflow at this time can be measured, Based on this, the air permeability can be calculated.
