The application of air permeability Tester in paper is mainly used to measure the air permeability of paper and evaluate its ventilation performance and filtration performance in practical applications. When performing air permeability testing, it is necessary to pay attention to the preparation of samples, the selection of test parameters, and the selection of test methods to ensure the accuracy and reliability of test results.

Steps for usage
| step | describe |
|---|---|
| 1 | Prepare paper samples, usually choose standard paper or paper in actual use as samples |
| 2 | Cut the paper sample to the appropriate size and record the area and thickness of the sample |
| 3 | Select the test method and test parameters according to the test requirements, such as gas flow, test time, etc. |
| 4 | Install the paper sample into the test fixture of the porosity Tester, and make sure the sample is flat and tight |
| 5 | Start the air permeability meter and perform the test. The testing instrument will test the air permeability of the paper sample |
| 6 | After the test is completed, evaluate the air permeability of the paper according to the test results |
When performing an air permeability test, the selection of test parameters should be adjusted according to different test requirements and sample characteristics, such as gas flow rate, test time, etc. In addition, the processing and selection of paper samples also need to meet the test requirements to ensure the accuracy and reliability of the test results. In addition, the air permeability meter should be operated correctly in accordance with the requirements of the operation manual during the test, so as to avoid errors in the test results or damage to the test instrument. The air permeability of paper will be affected by many factors, such as paper material, paper thickness, paper porosity and so on. Therefore, before testing, it is necessary to determine the test conditions and perform corresponding tests according to the test requirements. At the same time, it is also necessary to pay attention to the treatment and selection of test samples to avoid dirt on the surface of the samples or other defects that affect the test results. In the application of paper, air permeability Tester can help paper manufacturers and users evaluate the air permeability of paper, so as to improve paper manufacturing process and design, and improve product quality and performance.
The porosity Tester can also be used in paper applications to evaluate the air permeability of paper in packaging, filtration, hygiene and other fields. For example, in the packaging industry, air permeability meters can be used to evaluate the air permeability of packaging materials to ensure the quality and stability of packaging materials. In the field of filtration, the air permeability Tester can be used to evaluate the air permeability of filter materials to ensure the filtration effect and life. In the hygienic field, air permeability meters can be used to evaluate the breathability of sanitary products to ensure the comfort and protection of sanitary products.
