Lab Instrument for Measuring Leather Shoe Permeability
TQD-G1 is a specialized instrument designed to measure the air permeability of various decorating materials used in automobiles, such as polyurethane, expanded plastics, PVC, leather, textiles, and nonwovens. This testing ensures that materials meet practical application requirements by controlling their physical characteristics.
Professional Technology
- The instrument adheres to global automaker standards.
- Offers two test modes: fixed pressure difference to test flux and fixed flux to test pressure difference.
- Utilizes high precision sensors for electronic airflow and air pressure to ensure accurate test data.
- Controlled by a micro-computer with an LCD, menu interface, and PVC operation panel for ease of use.
- Includes a micro-printer and RS232 port for easy PC connection and data transfer.
Test Principle
- Method A: Measures air permeability by providing a constant air flux through the specimen and measuring the pressure difference.
- Method B: Measures air permeability by maintaining a constant pressure difference across the specimen and measuring the air flux over a specific area and time.
Standards Compliance
The instrument complies with multiple national and international standards, including ISO 9237, ISO 4638, ISO 5636, GB/T 10655, GB/T 5453, GB/T 4689.22, GB/T 13764, ASTM D737, TAPPI T460, and JIS P8117.
Applications
- Basic Applications: Suitable for testing air permeability in car decorating materials, elastic and porous polymer materials, textiles, and leather.
- Extended Applications: Applicable for testing air permeability in paper materials like tissue and toilet rolls.
Technical Specifications
- Pressure Difference Range: 0~1000 Pa
- Flux Range: 0~30 L/min
- Specimen Size: Method A: 52 mm x 52 mm; Method B: Diameter between Φ12 mm and Φ71 mm
- Port Size: Φ8 mm PU Tubing
- Instrument Dimensions: 502 mm (L) x 334 mm (W) x 298 mm (H)
- Power Supply: 220VAC 50Hz / 120VAC 60Hz
- Net Weight: 27 kg
Configurations
- Standard Configurations: Includes the instrument, micro-printer, grips, round sample cutter, and vacuum pump from America.
- Optional Parts: Professional software, communication cable, and customized grips are available.
Note: The gas supply port uses Φ8 mm PU tubing. Labthink is committed to continuous innovation and improvement, and technical specifications may change without notice. Visit www.labthink.com for updates. Labthink reserves the rights of final interpretation and revision.

PARAM® TQD-G1 Air Permeability Tester TQD-G1 is professionally designed for the determination of air permeability of decorating materials used in cars, e.g. polyurethane, nonwovens and other materials. Through the test, physical characteristics of materials could be controlled to meet practical application requirements. Professional Technology 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. This instrument 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 This instrument is applicable to the determination of: Decorating Articles of Cars Basic Applications Extended Applications Test the air permeability of car decorating materials, e.g. polyurethane, PVC, leather, textiles and non-woven materials Test the air permeability of elastic and porous polymer materials, e.g. Polymer Materials Test the air permeability of textiles, e.g. cloth and nonwovens Test the air permeability of leather Test the air permeability of paper materials, e.g. daily removable tissue and toil
