MVTR Tester / Moisture Vapor Transmission Rate Tester for flexible packaging MVTR Testing Introduction W301 2.0 MVTR Tester is based on the test principle of the gravimetric method (weight loss), and is developed, designed and manufactured in accordance with GB/T 1037, ASTM E96 and other standards. It is suitable for the water vapor transmission performance test of films, sheets, paper, packaging and related materials in the fields of food, medicine, medical equipment, daily chemicals, photovoltaic electronics, etc. It provides high, medium and low water vapor barrier materials Wide-range, high-efficiency water vapor transmission rate detection. Test principle Add distilled water to the dry and clean moisture-permeable cup, seal the moisture-permeable 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 is evaporated, and the evaporated water vapor passes through the film The drying device absorbs and measures the weight of distilled water in the moisture permeable cup with time to obtain parameters such as the moisture permeability of the sample. Standard ASTM E96/E96M, ASTM D1653, TAPPI T464, ISO 2528, DIN 53122-1, JIS Z0208, YBB 00092003, GB/T 1037, GB/T 16928
