TSY-T3 Water Vapour Permeability Tester is applicable in water vapour permeability test of barrier materials such as plastic film and laminated film. Users can control and adjust the technical index of packaging materials by testing the water vapour transmission rate. This equipment is designed and manufactured based on gravimetric method according to standards GB/T 16928, GB 1037, ISO 2528, JIS Z0208, ASTM E 96, and ASTM D 1653. The temperature and humidity of test chambers are controlled by microcomputer. Server controls and monitors the full procedure of test, easy to operate. Twelve chambers do the test at the same time, high in efficiency.
1. Test principle
Saturated water vapour transmits through specimen in a unit time under specified conditions of temperature and humidity. Determine the transmitted mass by test the decreasing weight of distilled water with time going.
