Water vapor transmission rate tester
Using the test principle of moisture-permeable cup weighing method, at a certain temperature, the two sides of the sample are formed with a specific humidity difference, and the water vapor penetrates the sample in the moisture-permeable cup into the dry side. By measuring the change in the weight of the moisture-permeable cup with time, parameters such as the water vapor transmission rate of the sample are obtained.
