Evaluating water vapor permeability of leather | WATER VAPOR PERMEABILITY TEST CHAMBER / No.203

Overview of LEATHER WATER VAPOR PERMEABILITY TESTER

This tester is used to evaluate the permeability of leather.
The operator is to cover the mouth of the container with the test specimen which is filled with silica gel.
The container is to be put on a turn table that turns at a constant speed and the surface of the test specimen is to be blown air by a fan for a certain amount of time. The permeability is to be calculated from the difference in weight of the container before and after the test.
