YINUO YN-TQD01 Schauber Air Permeability Tester

Instrument use

YN-TQD01 Schober air permeability Tester is used to measure the air permeability of various papers according to the Schober method. A constant pressure difference is formed by adjusting the water pressure on both sides of the instrument, and the air passing through a specific area of ​​the sample vertically for a certain period of time is measured. Flow, used to calculate parameters such as air permeability. It is widely used in the air permeability test of various industrial paper, food packaging paper, cement bag paper, paper bag paper, insulating paper, copy paper and other materials. It is suitable for paper mills, scientific research institutions and quality inspection departments of related materials.

Principle

The Principle of paper air permeability: under the specified conditions, under the unit time and unit pressure difference, the average air flow rate of the paper sheet per unit area, expressed in microns per pascal [1μm/(Pa･S)]=1mL/ (m2･Pa･S).
