A device for measuring the air permeability of textile materials MT-160. GOST 12088-77, GOST ISO 9237-2013 (VPTM-2 type)
A device for measuring the air permeability of textile materials MT-160. GOST 12088-77, GOST ISO 9237-2013 (VPTM-2 type)
The principle of operation of the device is based on the discharge of air in the measuring unit using a pump, the pressure drop during the passage of air through the sample is maintained constant, and the flow rate of air passing through a given area of the material under test per unit time is measured.
