Foam porosity tester foam permeability tester

Foam porosity tester
This porosity tester is used to measure the porosity of flexible porous polyurethane. The test principle is to put the test piece into the cavity, and the equipment will automatically apply continuous air pressure, and then test the difficulty of air passing through the porous structure of foam.
According to the standard:
ASTM D3574
Suitable for low, medium and high porosity three-stage foam. Customers can first set the pressure value on the touch screen, place the sample into a 50 * 50 * 25mm testing chamber, and then create a vacuum. After the test begins, the tester will automatically apply continuous air pressure and reach the differential value at a certain rate, completing the test.
