Air Permeability Tester for Assessing the Breathability of Leather Upholstery

Product Description

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

Test 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.
