It is suitable for woven, knitted, non-woven fabrics, and medical masks, providing reliable measurements for quality control, product development, and laboratory testing.\u003c\/p\u003e\n\u003cp\u003eThe Air Permeability Tester measures the pressure difference required to pass air through a test specimen at a controlled airflow rate. This enables accurate evaluation of the material’s air permeability performance. The instrument supports internationally recognized testing methods, including ASTM D737 and ISO 9237.\u003c\/p\u003e\n\u003ch3\u003eKey Features of the Air Permeability Tester\u003c\/h3\u003e\n\u003cp\u003eThe Permatest features an automatic specimen holder that makes sample placement quick and convenient. Press the holder to secure the test specimen and start the testing process.\u003c\/p\u003e\n\u003cp\u003eA built-in vacuum pump draws air through an interchangeable test head with a circular test opening. The system automatically maintains the preset test pressure and displays air permeability results digitally on the touchscreen control panel within seconds.\u003c\/p\u003e\n\u003cp\u003eWhen a different test nozzle or opening is required, the instrument provides a prompt for the appropriate change. After testing is completed, releasing the specimen holder automatically stops the vacuum pump, helping streamline the testing workflow.\u003c\/p\u003e\n\u003cp\u003eWith automated operation, digital result display, and support for ASTM D737 and ISO 9237, the Permatest provides an efficient solution for textile and fabric air permeability testing across a wide range of laboratory and quality control applications.\u003c\/p\u003e\n\u003ch2\u003eTextile and Fabrics Air Permeability Tester – Permatest Technical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table\" border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl\u003c\/td\u003e\n\u003ctd\u003eCan be controlled by the touch panel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003eThe result of air permeability test is displayed on the touch panel, units can be shifted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrinting\u003c\/td\u003e\n\u003ctd\u003eEquipped with printing function\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSoftware\u003c\/td\u003e\n\u003ctd\u003eEquipped with analyzing software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNozzles\u003c\/td\u003e\n\u003ctd\u003e11 nozzles are included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard Test Heads\u003c\/td\u003e\n\u003ctd\u003e20cm² and 38cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range\u003c\/td\u003e\n\u003ctd\u003e0.1~9999mm\/s (L\/m 2s)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTest Pressure\u003c\/td\u003e\n\u003ctd\u003e1 ~ 4000Pa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Thickness of Specimen\u003c\/td\u003e\n\u003ctd\u003e≤ 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Accuracy\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;+\/-2%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptional Test Heads\u003c\/td\u003e\n\u003ctd\u003e5cm², 25cm², 50cm², 100cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower\u003c\/td\u003e\n\u003ctd\u003e220 \/ 110 V, 50 \/ 60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e95kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (L*W*H)\u003c\/td\u003e\n\u003ctd\u003e1080 mm x 670 mm x 1080 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":52857681019191,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/textile-and-fabrics-air-permeability-tester-permatest1026176333.webp?v=1786978349","url":"https:\/\/qualitest.us\/fr\/products\/textile-and-fabrics-air-permeability-tester-permatest","provider":"Qualitest USA LC","version":"1.0","type":"link"}
