Foam Porosity Tester

This porosity tester is used to measure the porosity of flexible lar polyurethane. The test principle is to place the specimen in a cavity, and the equipment automatically applies continuous air pressure, then test how easy it is for the air to pass through the lar structure of the foam. It is applied to the ASTM D3574 standard and suitable for three-levels of low, medium, and high porosity foam.
