Abstract: TQY-Ⅲ automatic paper permeability meter was introduced, the meter contained electric circuit and air assemblies, including laminar flow elements, automatic pressure adjuster, automatic paper feeder,and etc.It had the functions of automatic measurement,sampling measurement,display,print,and data communication.Comparing with two imported paper permeability meters,the test results of TQY-Ⅲ were similar to A10 permeability meter.
