product manual:
         A highly hygroscopic material is placed in a round moisture-permeable measuring cup, and the cup mouth covers the test sample material, and the whole is a closed type, that is, the external water vapor can only be absorbed into the cup through the sample, and the cup mouth is fixed. The flow rate of temperature and humidity (RH%) is blown by the air, and the cup is rotated at a certain speed. After a certain period of time, the moisture permeability of the sample can be calculated.
