Paper air permeability tester TP-J10 is designed to measure the air permeability under specified conditions with time & unit pressure difference. It measures the average air flow through the unit area of the sheets. It is incorporated with standard ‘Paper porosity method’ used to test paper permeability. It is suitable for paper porosity with 1 x10 ˉ ² to 1 x10 ² µ m/ (Pa · S) range, and not suitable for large rough texture paper.
