Sell ​​High Precision Digital Air Permeability Tester for Textile Air Permeability Testing

DESCRIPTION / TECHNICAL SPECIFICATIONS

The Digital Air Permeability Tester is a state-of-the-art laboratory instrument specifically engineered to determine the resistance of materials to the passage of air. This device is highly suitable for testing a wide range of textile materials, including woven, knitted, and non-woven fabrics. Featuring a measurement accuracy of less than or equal to 1% FS, this instrument ensures highly reliable data for industrial research and quality control requirements.

Technically, the equipment offers an extensive measuring range from 0.5 to 10,000 mm/s, with a pressure differential range between 50 and 500 Pa. It supports multiple effective test areas, including standard 5 cm² and 20 cm², as well as optional sizes of 25 cm², 38 cm², 50 cm², and 100 cm². Equipped with 8 different orifice plates (nozzles) ranging in diameter from 0.5 mm to 26 mm, the device provides maximum flexibility for various sample thicknesses up to 5 mm.

The primary advantage of this Digital Air Permeability Tester is its comprehensive compliance with rigorous international standards. The device meets GB/T 5453, ISO 9237, ASTM D737, BS 5636, DIN 53887, and JIS L1096-A standards. Weighing 100 kg with physical dimensions of 700 x 1000 x 1000 mm, this instrument offers exceptional operational stability for long-term use in professional laboratory environments.
