Introduction:
The device is a constant temperature and humidity moisture permeability test device, which is suitable for sportswear and other requirements of the waterproof, moisture permeability of both the fabric, as well as plastic film, processed paper and other moisture-resistant packaging materials for the purpose of moisture permeability evaluation test.
Place a quantity of anhydrous calcium chloride into the empty moisture-permeable cup. Then install the sample and seal the moisture-permeable cup with the sample. The moisture permeable cup of the sealed package was placed in a laboratory for fixed temperature and humidity conditions for a period of time, and the moisture permeability of the sample was calculated by increasing the weight of anhydrous calcium chloride, thereby determining the moisture permeability of the sample.

Application:
The device is a constant temperature and humidity moisture permeability test device, which is suitable for sportswear and other requirements of the waterproof, moisture permeability of both the fabric, as well as plastic film, processed paper and other moisture-resistant packaging materials for the purpose of moisture permeability evaluation test.
