      【Scope of Application】
      

      The trace air permeability tester is a high-precision experimental test equipment integrating mechanics and electronics. It is suitable for testing the air permeability of materials with less air permeability under a certain pressure, and is used in products that require gas flow, such as acoustics. Membrane materials, waterproof and breathable film, tuning paper, micro-film, medical film, packaging film.
