Water Vapor Permeability Tester Principle
The device features a
rotating platform on which are 6 separate test stations and specimen holders
for each station. Holder necks part with silica-gel dryer are for placing
specimens which are fixed by screw cap. Weigh the holders with silica-gel dryer
and specimens respectively and lock them to the rotating chamber. After 7-8
hours weigh them again and calculate vapor penetration amount. The whole test
should be carried out in the specific atmospheric conditions ( the temperature
is set 20°C and humidity 65%). Besides the standard equipment, a built-in timer
is needed for test timing.
