Moisture permeability tester
The moisture permeability testing machine can test the moisture permeability of textiles, plastic films and paper.
Water vapor permeability is usually expressed by two indicators: water vapor transmission rate (WVT) or water vapor transmission coefficient (PV). The moisture permeability testing machine is usually used in conjunction with a moisture permeability cup, an analytical balance, and an oven.
There are three commonly used test methods:
1. A-1 method (calcium chloride)
2. Method A-2 (Water Method)
3.B method (potassium acetate method).
