Bekk Smoothness Tester (HS Model)

Smoothness of paper is one of the important factors to evaluate writing and printing aptitudes of paper. With this machine, test is conducted in the following procedure: place a sheet of paper on the well-polished surface of glass constituting an optical surface, apply a 0.1 MPa pressure on the top of the paper and measure the time needed for a 10cc air to penetrate through the gap between the paper surface and the glass surface. To solve the problem of consumption of much time for measurement of specimens with a high smoothness, a rapid measurement system also is provided, which is able to measure penetration time of 1cc air, 1/10 of the standard air volume. For specimens of high smoothness, it is possible to supplement 0.25cc, 1/40 of the standard air amount (optional).
