Product Description


ASTM D737 Automatic Fabric Air Permeability Tester, to test the air permeability of various woven fabrics, knitted fabrics, non-woven fabrics, industrial filter materials etc.



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



  1. Touch screen control, Chinese and English menu, man-machine dialogue mode, easy to operate.
  2. The built-in thermal printer is convenient for quickly printing the test results on site.
  3. This instrument uses a high-precision differential pressure sensor to replace the traditional water column differential pressure test.
  4. The computer calculates the test data, eliminating the need for manual conversion and table lookup.
  5. The nozzle can be automatically replaced according to the measurement range of each nozzle, and the test area can be automatically detected, which makes the operation simple and easy, and the accuracy and efficiency are higher.
  6. It can be operated on-line with the upper computer of the computer, and the real-time test data curve can be automatically drawn for easy observation.
  7. The test parameters can be set directly by numbers, and the parameter units can be set according to the needs.
  8. The sample fastening device is controlled by the cylinder. When the experiment is started, it will automatically clamp the sample, and there is enough pressing force to ensure the tight fit of the sample fixture.
