Introduction
The air permeability tester is used to measure the air permeability of the sample through the rate of the sample under the specified test area, pressure drop and time conditions. The automatic pressure difference test system can be used to calculate the air permeability of the tested sample quickly and accurately in a very short time.
Application
The equipment is suitable for outdoor textiles, such as airbags, clothing, parachutes, sails, tents and awnings, etc ; all weather and rainproof fabric; sportswear and functional textiles; weathering material performance assessment; military and industrial use materials permeability Testing; the development and research of air filter materials and vacuum vacuum cleaner bags etc; all kinds of paper products.

Features
Press the test head with the electromagnetic induction system. Start automatically test After pressing the clamp. multi-size test head can be replaced, to meet different test standards. Platform handle with roller feet is easy to move.
Automatic identification function. When you replace the test head, the system can automatically identify different sizes of test head, and in accordance with the corresponding size of the test and data analysis records, without manual selection. you can avoid test error in maximum extent.
WIFI data connection, with high compatibility Andrews system test software, can quickly and accurately test the air permeability of the sample at the same time, and can obtain more remote monitoring and mobile use.
