Test prensibi

Using the test principle of weighing method of permeable cup, a specific humidity difference is formed on both sides of the sample at a certain temperature, and the water vapor enters the dry side through the sample in the permeable cup. By measuring the change of the weight of the permeable cup with time, the water vapor transmittance of the sample is obtained.
