DRK121 Air Permeability Tester Introduction: The DRK121 Permeability Tester is designed and manufactured specifically for testing the permeability of various types of paper, including cement bag paper, paper bag paper, cable paper, copy paper, and industrial filter paper. This tester is suitable for papers with a permeability ranging from 1×10-2 to 1×102 um/（Pa.S）. However, it is not suitable for papers with a rough surface. Technical standards: QB/T1667-98 "Permeability Tester for Paper and Paperboard"; GB/T458-1989 "Method for Determining Permeability of Paper and Paperboard" (Xiao Boer); ISO1924/2-1985, QB/T1670-92, and other relevant standards; Technical Specifications: Measurement range: 0-17 μm/(Pa·s) Test area: 10.0±0.05cm Measurement accuracy: For volumes less than 100ml, the volume error is 1ml; for volumes greater than 100ml, the volume error is 5ml Pressure difference applied to the sample: 1.00±0.01kPa Sample size: 60*100 mm The coaxiality of the central holes of the upper and lower clamping rings should not exceed: 0.05mm Outline dimensions: 350*250*1160mm Weight: Approximately 32kg Environment: In a clean environment with a room temperature of 20±10°C, placed on a solid and stable workbench
