Product Descriptions
Application
W533 Water Vapor Permeability Analyzer test the water vapor transmission rate of various materials, including: plastic film, composite film, aluminum-plated film, aluminum foil etc.; sheets, such as PP sheet, PVC sheet, rubber, building material, porcelain; other application, such as solar panel, paint film, medical patch etc. It is widely used in packaging, plastic film, food, pharmaceuticals, personal care industries, inspection agency, research institute, college and so on.
Working Principle
Gravimetric method. Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room; humid gas flows in upper room, and place desiccant device in lower room; as in lower room it remains dry (0-8%RH) by desiccant, water molecules penetrate through the sample from upper room into lower room, absorbed by desiccant; then the cup weight will increase; system weigh the increasing cup weight so as to calculate the water vapor transmission rate.
