Air permeability testers are essential instruments used to measure the porosity or the breathability of materials such as fabrics, papers, and plastics. Selecting the right air permeability tester for your application is crucial to ensure accurate and reliable results. In this article, we'll discuss the key factors to consider when choosing an air permeability tester.

1. Test Method

The first factor to consider when selecting an Air permeability tester for fabric is the test method. There are various test methods available, including pressure drop method, Frazier method, and Gurley method, among others. Each method has its advantages and limitations, so it's important to choose a method that best suits your application.

2. Testing Standards

The second factor to consider when selecting an air permeability tester is the testing standards. Different industries have their testing standards, such as ASTM, ISO, and TAPPI, among others. It's crucial to choose an air permeability tester that complies with the relevant standards for your industry to ensure the accuracy and reliability of your results.

3. Sample Size and Type

The third factor to consider when selecting an fabric air permeability tester is the sample size and type. The size and type of the sample can affect the accuracy and reliability of the results. Different air permeability testers have different sample sizes and types they can accommodate. It's important to choose an air permeability tester that can handle the size and type of sample you're testing.

4. Automation and Ease of Use

The fourth factor to consider when selecting an air permeability tester of textile fabrics is the automation and ease of use. Automation can improve the accuracy and repeatability of the results, as well as reduce the testing time. Ease of use is also essential, as it can reduce the risk of user error and increase the efficiency of testing.

5. Cost

The fifth and final factor to consider when selecting an air permeability tester is the cost. Automatic Fabric Air Permeability Tester can vary in price, and it's essential to choose an air permeability tester that fits within your budget. However, it's also important not to compromise on quality to save costs, as inaccurate or unreliable results can be costly in the long run.

1. The ASTM D737 Air permeability tester is a testing instrument that utilizes the pressure drop method to measure the air permeability of textile fabrics. In this method, a sample is placed over a defined area of a test cell, and air is drawn through the sample at a constant rate. The pressure drop across the sample is then measured, and this value is used to calculate the air permeability of the material.

2. Automatic Air Permeability Tester Standards:

GB/T 5453, GB/T 13764, ISO 9237, ISO 7231, ISO 5636, BS 5636, ASTM D737, DIN 53887, JISL1096, AFNORG 07-111, EDANA140.1,  ISO 9073-15

3. Automation & Sample Size and Type

3.1. Microcomputer processing without manual calculation and the test result can displayed directly.

3.2. Air Permeability Tester For Textiles Equipped with thermal printer to print the experiment result.

3.3.Touch Screen Control as well as operating by connect to the computer.
