5Pages
Catalog excerpts
Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 TQD-G1A Air Permeability Tester is applicable to the test of air permeability and air resistance of automotive interior decoration materials, such as polyurethane foam, PVC, leather, textiles, nonwovens etc. In addition, it can also be used to test the permeability of separation membrane, sponge, carpet, non-woven fabric, paper and leather. Through measurement, the performance control of materials is realized to meet the needs of practical application of products. Two measurement methods of constant pressure difference and constant flow can be freely selected. High precision electronic air flow and air pressure sensors ensure the accuracy of test data. Built-in imported maintenance-free vacuum pump system for better airflow stability. Professional sample fixture for safer operation. Pneumatic clamping of the sample saves time and labor, and the clamping force is consist
