Many kinds of paper used in real work and life, such as cement bag paper, paper bag paper, cable paper, copy paper and industrial filter paper, etc., need to measure the size of their air permeability. This instrument is designed and manufactured for the above-mentioned various papers. . This instrument is suitable for paper with air permeability between 1×10-2~1×102um/(Pa.S), not suitable for paper with rough surface.

Features

That is, under the specified conditions, under the unit time and unit pressure difference, the average air flow through the unit area of paper.
