TQD-1 Air Permeability Tester

Brief Introduction 

Air permeability tester TQD-1 is professionally designed for the determination of air permeability of decorating materials used in cars, separation membrane, sponge,carpet,non-woven fabric, leather,PVC,textiles and other materials. Through the test, physical characteristics of  materials could be controlled to meet practical application requirements.

Technical 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

- Embedded high-speed microcomputer chip control, simple and efficient human-computer interaction interface, providing users with a comfortable and smooth operating experience

- Standardization, modularization, and serialization design concepts can meet the individual needs of users to the greatest extent

- 7 inch high-definition color LCD touch screen, UI interface, real-time display of test data

- Imported high-speed and high-precision sampling chip, effectively guaranteeing test accuracy and real-time performance

- Overvoltage safety protection design

- 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.
