Water vapor permeability tester (Gravimetric) SX-W301

APPLICATION:
This machine is suitable for the test method of the impact resistance degree of shoes (head). Electromagnet is used to control the rise and fall of the impact head and check the damage of the toe steel head after striking the toe steel head of the shoe with a certain height. The energy of each impact is measured.
Test principle:
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
