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.

Test Standards

TQD-G1 air permeability tester conforms to the multiple national and international standards: ISO 9237, ISO 4638, ISO 5636, GB/T 10655, GB/T 5453, GB/T 4689.22, GB/T 13764, ASTM D737, TAPPI T460, JIS P8117

Applications

TQD-G1 air permeability tester is applicable to the determination of:

Basic Applications
Decorating Articles of Cars Test the air permeability of car decorating materials, e.g. polyurethane, PVC, leather, textiles and nonwovens materials

FAQ's of Air Permeability Tester for Assessing the Breathability of Leather Upholstery:

Q: How does the Air Permeability Tester operate to assess leather breathability?

A: This instrument measures the pressure differential and air flow passing through a leather specimen clamped in an aluminum alloy holder. The digital automatic control adjusts test speed and air flow, complying with ASTM D737 and ISO 9237 standards.

Q: What materials and environments can the tester be used for?

A: While primarily designed for leather upholstery, the tester can evaluate various seat and textile materials. Suitable for laboratory and industrial applications, it operates efficiently in environments with 45-85% relative humidity and 15C-35C temperature.

Q: When should I use this tester for optimal performance and results?

A: It is best utilized during quality control, research, and material development stages when accurate breathability data is needed. The system should operate within specified environmental conditions and be powered by a 220V AC supply.

Q: Where can I install or mount the Air Permeability Tester?

A: The tester is designed for tabletop or benchtop mounting, making it suited for laboratories, manufacturing quality control rooms, and research facilities.

Q: What is the process for conducting a test using this machine?

A: Place a 40 mm diameter specimen into the holder, configure the test parameters via the digital controls, and initiate the automatic test. The system measures and displays air permeability in real-time, storing up to 250 results for later analysis.

Q: How is data displayed and managed after testing?

A: Test results are shown on a large digital LCD screen with clear readings and status indicators. Data can be stored in the internal memory and exported via the RS232 interface as needed.

Q: What are the main benefits of using this Air Permeability Tester?

A: The device provides high accuracy (2%), rapid response, automatic safety features, low maintenance due to its oil-free pump, bilingual support (English/Chinese), and the ability to handle diverse testing requirements for leather and seat materials.
