Water Vapor Permeability Tester QT-Q301-WVTR Overview:
The QT-Q301-WVTR Single Cell Water Vapor Permeability Tester, also known as the Water Vapor Transmission Rate Analyzer, operates on the gravimetric method (weight loss) for testing. This cutting-edge QT-Q301-WVTR system is designed, developed, and manufactured in strict accordance with ASTM E96 and other international standards.
It is an ideal solution for evaluating the water vapor transmission performance of films, sheets, paper, packaging, and related materials in various industries such as food, medicine, medical equipment, chemicals, and photovoltaic electronics. The QT-Q301-WVTR system ensures precise detection of water vapor transmission rates for high, medium, and low water vapor barrier materials. Qualitest also provides a 3-station version of this WVTR Analyzer for applications with higher testing demands.
Test Principle
To conduct the test, add distilled water to the dry and clean moisture-permeable cup, seal the cup with a pre-treated sample, and place it in the test chamber. By controlling the temperature and humidity, the distilled water in the moisture-permeable cup evaporates, and the resulting water vapor passes through the film.
The drying device absorbs and measures the weight of distilled water in the moisture-permeable cup over time, allowing the determination of parameters such as the moisture permeability of the sample. This process is crucial for assessing the efficiency of the QT-Q301-WVTR Single Cell Water Vapor Permeability Tester.
