DRK255 Constant Temperature and Humidity Test Chamber Fabric Moisture Permeable Meter (with moisture permeable cup)

Test items: Measure the moisture permeability of various fabrics, including moisture-permeable coated fabrics.

Technical Description:
It is mainly used to determine the moisture permeability of various fabrics, including moisture-permeable coated fabrics. Structural principle: Computer control is used to create a constant temperature and humidity test environment. In the constant temperature and humidity test environment, 6 moisture-permeable cups are placed, and the sample is placed in the cup and sealed with a rubber gasket. For the water seal, the moisture-permeable cup of the fabric sample is placed in a sealed environment with a specified temperature and humidity, and the moisture permeability is calculated according to the change in the mass of the moisture-permeable cup (including the sample and the moisture absorbent or water) within a certain period of time.
