The air permeability tester is designed and manufactured for cement bag paper, paper bag paper, cable paper, copy paper and industrial filter paper, etc., to measure the size of its air permeability, the instrument is suitable for the air permeability between 1×10-2~1×102um/ (pa.s), not for the paper with large rough surface.
That is, under the specified conditions, unit time and unit pressure difference, unit area of paper through the average air flow. Many kinds of paper, such as cement bag paper, paper bag paper, cable paper, copy paper and industrial filter paper, need to measure its permeability, this instrument is designed and manufactured for all kinds of paper. This instrument is suitable for the air permeability between 1×10-2~1×102um/ (pa. S), is not suitable for the surface of large rough paper.
The breathability meter conforms to QB/T1667-98 “Paper and cardboard breathability Tester”, GB/T458-1989 “Paper and cardboard breathability determination Method” (Schobol). Iso1924/2-1985 QB/T1670-92 and other relevant standards.
