DESCRIPTION:

Smoothness, Porosity & Softness Tester measures average Smoothness, Porosity and Softness of paper and films by determining the time necessary for a certain volume of air to flow through the inserted sample, under a uniform pressure. Air is forced downward at a low uniform pressure through an open tube to the upper orifice plate against which the sample is clamped. Each 50cc of air is marked and the test consists of timing the amount of air used in any three ways listed below:

Smoothness Test    :  Lateral flow between several sheets.

Porosity Test           :  Rate of flow through one square inch.

Softness Test          :  Rate of flow over the surface.

SALIENT FEATURES:
