WVTR(water vapor transmission rate) Analyzer is applicable in WVTR analysis of barrier materials such as plastic film and laminated film. Labthink has WVTR Analyzers that comply with humidity detection method, electrolytic detection method and gravimetric test method respectively. WVTR Analyzers conform to standards of ASTM E96, ASTM D1653, ASTM F1249,ASTM E398, ASTM F372, ISO 2528, ISO 15106-1, ISO 15106-2, ISO 15106-3, DIN 53122-1, DIN 53122-2,JIS Z0208, JIS K7129 TAPPI T464, TAPPI T523, TAPPI T557, GB 1037,GB/T 16928.

Test principle: saturated water vapor transmits through specimen in a unit time under specified conditions of temperature and humidity. Determine the transmitted mass by testing the decreasing weight of distilled water with time going.
