The Fabric Air Permeability Tester has the advantages of simple operation and accurate measurement, and it can be tested directly on the sample. The test is to measure the air permeability of the sample by measuring the pressure difference between the two ends of the orifice plate. In order to measure fabrics with different air permeability, the instrument is equipped with a set of orifice plates with different pore sizes for optional use, especially for tests with different pore sizes, which will have an excellent performance. The test area of the sample clamp through hole is 20cm2 as the standard configuration of the instrument, and the optional configuration is shown in the main parameter requirements.

The main parameters:

01. Pressure difference range: 50～500Pa;

02. Measuring range: 0.167～15000mm/s;

03. Measurement error: ≤±2%;

04. Thickness of tested fabric: ≤12mm;

05. Suction volume adjustment: automatic dynamic adjustment;

06. Sample area fixed value circle: 20cm2 (Ф50mm) standard, (or customize a sample area according to the user);

Users of other areas can order separately: 5cm2; 25cm2; 38cm2 (Ф70mm); 50cm2; 100cm2;

07. Method of measuring flow pressure difference: automatic conversion of orifice plate type;

08. Orifice plate: 8 holes (automatic conversion);

09. Orifice plate conversion: adaptive, automatic switching;

10. Display mode: large-screen LCD Chinese display;

11. Control method: microcomputer control, high-precision low-dropout sensor dynamic measurement, professional test analysis software contains professional mathematical models to make the test automatically completed, even if the test is between different sizes of apertures, the test data will be kept consistent;

12. Setting method: digital setting, the unit can be switched as needed;

13. Working mode: the sample is automatically compressed, and the orifice plate detects the air volume and the flow rate is stable and self-adapting.
