The DRK121 air permeability meter is designed and manufactured for cement bag paper, paper bag paper, cable paper, copy paper and industrial filter paper, etc., to determine the size of its air permeability. This instrument is suitable for air permeability of 1×10-2~1×102um/ (Pa.S) between the paper, not suitable for the rough surface of the paper. Features That is, under specified conditions, the average air flow rate per unit area of ​​paper passing through unit time and unit pressure difference. Applications Many kinds of paper, such as cement bag paper, paper bag paper, cable paper, copy paper and industrial filter paper, need to measure the air permeability. This instrument is designed and manufactured for the above-mentioned papers. This instrument is suitable for paper with air permeability between 1×10-2~1×102um/(Pa.S), but not suitable for paper with rough surface. Technical Standard The instrument complies with QB/T1667-98 "Paper and Board Air Permeability Tester", GB/T458-1989 "Paper and Board Air Permeability Test Method" (Shobel). ISO1924/2-1985 QB/T1670-92 and other relevant standard requirements. Product Parameter
