Compression Porometer.

Porous Materials recently introduced the "Cyclic Compression Porometer" for measuring porosity changes over time. The Porometer can test for liquid and gas permeability, the Frazier and Gurley number, Bubble point, mean flow pore diameter and pore size distribution. The system requires a computer with Windows 95/98, a compressed gas source and a sample with a 6-43 mm diameter and a thickness of up to 2 cm.
