Paper and Cardboard Air Permeability Tester N600P Introduction Paper and cardboard air permeability tester N600P is designed and developed according to ISO5636 and other standards. It adopts the testing principle of differential pressure method and combines Gurley method, Schauer method and Bengtsen method. The method is integrated into one machine and is suitable for the air permeability of various papers and cardboards. It can test the air permeability, air permeability resistance, transmission rate and transmission volume of materials. Test principle Gurley method: Measure the time it takes for 100 mL of gas to pass under a constant pressure difference of 1.23 kpa. Schober method: constant pressure difference 1.00 kPa±0.01kPa or 2.50±0.01 kPa, select the appropriate test duration, and measure the air flow through the sample through the test volume. Bentsen method: Under a constant pressure difference of 1.47 kPa, after clamping for 5 s, test the air flow through the test surface. Standard ISO 5636-5：2003, ISO 5636-2：1984, ISO 5636-3：2013, TAPPI T460, GB/T 458-2008, SJ/T 10171-2016 Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

Specification Test Range ♦ Integrate Gurley's method, Schober's method, and Bengtsen's method into one machine for users to choose freely to meet the testing needs of different users; ♦ The pressure difference of the instrument is adjustable in the range of 0~5 kPa, with an accuracy of 0.001 kPa, fully meeting the test pressure difference requirements of the three methods; ♦ The test area can be freely converted between 10.0 cm2 and 6.42 cm2 by changing the fixture; ♦ The instrument comes with a temperature and humidity sensor that monitors the temperature and humidity of the test chamber in...
