The No. 4190 was originally developed to test the printing quality of paper. In more recent years, its use has spread to other industries in testing or checking other material surfaces for smoothness, softness or porosity. In dealing with the printability of paper, it has been found that smoothness is the most important factor in printing quality and softness is usually secondary. The Gurley No. 4190 S-P-S Tester measures a given air flow through the sample for porosity tests and leakage across its surface(s) for softness or smoothness tests. This is accomplished by changing a variety of adapter and clamping plates. This model is identical to the No. 4110 and 4140 for porosity tests and their components.
