Product Overview
  • Principle

    Method A

    Providing a constant air flux going through the specimen vertically, the air permeability could be obtained by measuring the pressure difference.

    Method B

    Providing the constant pressure difference between two sides of the specimen, the air permeability could be obtained by measuring the air flux through specific area in the certain time.

    Basic Applications

    Decorating Articles of Cars

    Test the air permeability of car decorating materials, e.g. polyurethane, PVC, leather, textiles and nonwovens materials.

    Elastic and Porous Polymer Materials

    Test the air permeability of elastic and porous polymer materials, e.g. sponges.

    Textiles

    Test the air permeability of textiles, e.g. cloth and nonwovens.

    Leather

    Test the air permeability of leather.

    Extended Applications

    Paper

    Test the air permeability of paper materials, e.g. daily removable tissue and toilet rolls.

    Features

    • This instrument is designed according to the standard requirements of global automakers.
    • 2 test modes are available for customers: fix pressure difference to test flux and fix flux to test pressure difference.
    • High precision sensors of electronic airflow and air pressure to ensure the accuracy of test data.
    • The instrument is controlled by micro-computer, with LCD menu interface and PVC operation panel, which is convenient for customers to operate or view test data.
    • Equipped with micro-printer and standard RS232 port for easy connection with PC and data transfer.
