W3/031 Water Vapor Transmission Rate Tester (WVTR) Product Sample

W3/031 Water Vapor Transmittance Tester (WVTR)Based on the cup test principle, it is a professional water vapor transmission rate (WVTR) tester for thin film samples; The three moisture permeable cups configured in the system can be independently tested, and the testing process not only strictly meets the standard requirements, but also has automated control.

W3/031 Water Vapor Transmittance Tester (WVTR)Testing principle:
W3/031 adopts the principle of moisture permeable cup weighing method for testing. At a certain temperature, a specific humidity difference is formed on both sides of the sample. Water vapor passes through the sample in the moisture permeable cup and enters the dry side. By measuring the change in weight of the moisture permeable cup over time, parameters such as the water vapor transmission rate of the sample can be determined.
