Air Permeability

To measure accurately the Smoothness & Air Permeability (or Porosity) of materials such as paper and cardboard, wovens, plastics and membranes.

• 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 (or compressibility) of materials tested..
• Manual and automatic units available.
