What should be paid attention to when using the air permeability tester?

The air permeability test method usually uses an instrument called "Air Permeability Tester" for testing. Air Permeability Tester is a special device for measuring the air permeability of materials. It can measure the air permeability of various materials, including paper, fabric, non-woven fabric, filter material, etc.

When using the Air Permeability Tester to test the air permeability of materials, the following items need to be paid attention to:

1. Select the appropriate test instruments and test methods according to the test requirements to ensure the accuracy and reliability of the test results.

2. When preparing the sample, it is necessary to ensure that the size and shape of the sample meet the test requirements, and the surface of the sample should be flat without obvious damage or stain.

3. The test instrument needs to be calibrated before the test to ensure the accuracy of the test results.

4. It is necessary to operate strictly in accordance with the test requirements during the test, such as applying standard pressure, adjusting test time or flow, etc.

5. During the test, it is necessary to avoid the interference of external factors on the test results, such as wind, water vapor, temperature and humidity.

6. After the test, it is necessary to clean the test instrument in time, and keep the test results and samples properly.

In short, when using the Air Permeability Tester for testing, it is necessary to carefully read the test requirements and operating instructions, and strictly follow the requirements to ensure the accuracy and reliability of the test results.
