Leather Air Permeability Tester

Testing Protocol
Measures breathability via differential pressure sensors (±0.5 Pa) as air passes through leather samples (10 cm² area) at 10–50 L/min. Porosity mapping identifies weak zones using 3D laser scanning.

Performance Metrics

• Airflow Rate: 0.1–500 L/min with ISO 11092 compliance.
• Water Vapor Transmission: Up to 1,500 g/m²/24h for equestrian saddles.

Application

• Footwear: Ensures breathable linings for hiking boots.
• Upholstery: Tests car seats for odor reduction.
• Historical Conservation: Preserves antique leather artifacts.

Sustainability Impact
Guides eco-friendly tanning processes (e.g., chromium-free) by highlighting permeability trade-offs.

Technology Edge
Patented vacuum-seal technology eliminates sample slippage, outperforming manual methods (e.g., Textest).
