- Precision Clamping System: Ensures airtight sealing, ideal for non-rough papers such as cement bags, cable papers, and copy papers.
- High Accuracy Standards: Delivers highly accurate air permeance results with minimal volume error, adhering to ISO and GB/T 458 requirements.
- Standardized Test Area: The test area measures precisely 10 ± 0.2 cm² with an exact pressure differential of 1 ± 0.01 kPa, following ISO 5636 guidelines.
How the Breathability Testing Instrument Works
The TQD-01 Breathability Testing Instrument operates on the Schopper method, placing a sample securely between two airtight circular gaskets. During testing, a constant pressure differential is applied across the test area, allowing the instrument to calculate the air permeance by measuring the air flow through the material in a specified period. This method ensures that each test conducted is reliable and repeatable, crucial for lab accuracy.
