W401 2.0 Water Vapor Transmission Rate Tester is designed and manufactured according to ASTM F1249, BS EN ISO 15106-2 standard, based on the test principle of infrared moisture analysis sensor, used to test the water vapor transmission rate (amount) of samples under certain conditions, and is often used for evaluating Barrier properties of packaging materials.
W401 2.0 is a high-precision instrument that upgrades the overall technology and appearance of the W401 series, with a resolution of up to 0.0001 g/(m2·24h). Suitable for plastic film, composite film, sheet, metal foil and other sheet samples; customizable fixtures are suitable for packaging containers, such as bottles, bags, bowls and other packaging items. It can also be applied to samples such as solar backplanes, LCD screen films, and medical patches.
Test principle
The W401 2.0 water vapor transmission rate tester uses the principle of infrared method.
