Gurley Densometer

Gurley Densometer

Densometers are the accepted standard for measuring the porosity of materials such as papers, wovens, plastics and membranes.
All Densometers measure the time required for a given volume and of air (25cc to 400cc) to flow through a standard area of material being tested under light uniform pressure. Certain models, such as the S-P-S Tester, are also used to measure surface smoothness and material softness.
