36L Water Vapor Permeability Tester with Computer -HTZ C2

36L Water Vapor Permeability Tester with computer

C2 can performs testing on packaging materials, such as plastic film, composite film, co-extrusion film, geo-membrane, aluminum-plated films and foils, infusion bag, sheets, paper, paper board, solar battery panel, cellophane, and various packaging materials.


ISO 2528, ASTM E96, ASTM D1653, GB 1037, GB/T 16928, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003


Test dishes filled with distilled water in a controlled dry atmosphere, a constant humidity difference is generated between two sides of the test specimen, the water vapor permeates through the specimen and into the dry side, water vapor transmission rate and other parameters can be obtained by measuring the weight changes of the test dish in different time.
