Water Vapour Permeability Tester For Testing Lab

Water Vapour Permeability Tester - The Water Vapour Permeability of leather, that is its ability to allow moisture to pass through it, is of considerable importance, especially when the leather under test is being used for manufacture of apparels.   Water vapour permeability of leather is evaluated by clamping a circular test specimen over the mouth of a bottle containing a solid desiccant and subjecting it to a rapid current of air. The air inside the bottle is circulated by keeping the desiccant in motion. The increase in weight of the bottle over a specified interval of time gives the quantitative measure of the water vapour permeability of the leather sample, under test. civil lab equipments manufacturers
