TMI Densometer Model 58-03 measures air permeability (Gurley type) of sheet like materials including Paper, Paperboard and nonwovens. Porosity of paper or density is an important measurement when simulating conditions where paper is picked up under vacuum.
Air resistance by the Gurley method measures the amount of time in seconds for a specific volume of air to pass through the voids in a sheet of paper under a specified clamping pressure.
The Gurley type porosity tester is similar to the Bendtsen air permeance tester, see catalog # 58-21 Roughness and Air Permeance Tester.
