Introduction: N800 paper permeability tester is a set of machinery, electronics as one of the high-precision test equipment used. Suitable for paper, cardboard breathability test. Products comply with GB / T 22819, GB / T 458-2008 and other standards. The working principle of the instrument is to determine the air flow rate of a given area vertically passing the sample within a certain time under the specified pressure difference condition to calculate the air permeability. Features: 1 According to GB / T 22819 design and manufacture, the pressure can be adjusted, automatic measurement and calculation of the results. 2 host with powerful computing capabilities, automatic calculation of the results. 3 test area of 10cm2. 4 is simple and easy to operate. 5 dynamic test data show at a glance. 6 support different unit conversion. Technical Parameters : Measuring range: 0.1 ~ 39000μm / (Pa.s) Measurement accuracy: 0.1μm / (Pa.s) Pressure range: 0.1-1500Pa Test area area: 10cm2 Sample thickness: ≤ 10mm Power: 220V, 50Hz Overall dimensions: 800mm × 330mm × 650mm
