Water Transmission Rate Tester W3 / 030 didasarkan pada metode cup, dan secara profesional berlaku untuk tes tingkat transmisi uap air film plastik, film komposit, lembaran dan bahan lainnya yang digunakan dalam industri medis dan konstruksi. Dengan menguji laju transmisi uap air, indeks teknis material dapat dikontrol untuk memenuhi persyaratan produksi.
Under a certain test temperature, 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. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.
This test instrument conforms to the following standards:
ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003
This instrument is applicable to the determination of water vapor transmission rate of:
