SMOOTHNESS, POROSITY & SOFTNESS TESTER (GURLEY TYPE) For testing the 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. C. HIGH PRESSURE POROSITY & SOFTNESS TESTER (GURLEY TYPE) For measuring the high pressure porosity & 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. Electronic self starting timer as an optional accessory, for automatic measuring of either 25, 50, 100, 150, 200 or 300cm3 air to pass through the test specimen.
