Spessimetro DP71

Laboratory equipment to test the thickness of any kind of leather of any tannage.

The measurement is valid for both the whole leather and the test sample.
Leather is placed under a specified load for a specified time and the thickness is promptly available.
This apparatus is fitted with the following elements:
Graduated gauge to read to 0,01 mm directly with an accuracy of ± 0,02 mm over the whole scale length;
Anvil, comprising the flat horizontal surface of a cylinder of diameter 10,00 mm ± 0,05 mm projecting 3,0 mm ± 0,1 mm above the surface of a concentric flat circular platform of diameter 50,0 mm ± 0,2 mm;
Presser foot, having a flat circular surface of diameter 10,0 mm ± 0,05 mm, coaxial with the anvil and capable of movement normal to the face of the anvil. The contacting surfaces of the anvil and presser foot shall be dead weight loaded with 393 g ± 10 g. Movements of the presser foot shall give a direct reading of the movement on the gauge;
Rigid stand, to hold the gauge, anvil and presser foot.
