Leather Air Permeability Tester

Leather Air Permeability Tester 

Product Description: This machine is used to measure the water vapor permeability of various leather, artificial leather and textile materials. The principle is to fix the circular test piece on the opening of a test bottle containing a certain amount of solid desiccant in the water vapor penetration testing machine, so as to use the test piece to separate the desiccant in the bottle from the air outside the bottle. , By starting the water vapor penetration tester to make the test bottle rotate and the fan that disturbs the air to rotate, the continuously moving desiccant continuously absorbs the water vapor passing through the test piece, and the desiccant absorbs water by weighing the test bottle within a certain period of time. The mass of the vapor is used to evaluate the water vapor permeability of the test material.
