W3/060 Weighing Method Water Vapor Transmission Rate (WVTR) Testing System Product Sample

W3/060 Weighing Method Water Vapor Transmission Rate (WVTR) Testing SystemSuitable for measuring the water vapor transmission rate of various materials such as plastic films, composite films, medical and construction fields. By measuring the water vapor transmission rate, the technical indicators for controlling and regulating packaging materials and other products can be achieved.

W3/060 Weighing Method Water Vapor Transmission Rate (WVTR) Testing SystemTechnical features:
1. Professional - W3/062 is a specialized water vapor transmission rate (WVTR) testing system for thin film samples based on the cup test principle. It can detect water vapor transmission rates as low as 0.1g/m2 • 24h; The configured high-resolution weighing sensor provides system sensitivity while ensuring high accuracy.
2. W3/062 adopts a precise circular tray design, which can accommodate 6 breathable cups at the same time and test 6 different samples at the same time; One host can expand and connect to 9 satellite machines, easily achieving parallel testing of 60 samples.
3. Intelligence - W3/062 is equipped with Labthink's next-generation operating software, featuring a user-friendly interface and intelligent data processing capabilities; At the same time, in the local area network environment, it also supports the LystemTM laboratory data management system to centrally manage test results and reports.

W3/060 Weighing Method Water Vapor Transmission Rate (WVTR) Testing SystemTesting principle:
W3/062 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. During the weight loss method, the testing chamber is on the dry side, while during the weight gain method, the testing chamber is on the wet side.
