Whole shoe breathability and heat preservation testing machine/ Footwear Breathability and Insulation Tester / Shoe Air Permeability Tester
Standard
- SATRA TM376: Thermal insulation testing of footwear with sock integration.
- SATRA TM386: Water vapor permeability assessment for athletic and outdoor footwear.
- SATRA TM436: Comprehensive sweat management evaluation for industrial safety shoes.
Product Advantages
1. Holistic Performance Analysis
- 3-in-1 Testing: Simultaneously evaluates thermal insulation, moisture absorption, and air permeability.
- Real-World Simulation: Replicates in-shoe microclimates with sweat generation and dynamic airflow.
2. Anatomical Precision
- Articulated Foot Model: Mimics human foot biomechanics with 22 articulating joints.
- Sock-Integrated Testing: Accounts for material interactions with standard/athletic socks (cotton, merino, synthetic).
3. Versatile Applications
- Multi-Category Use: Validates sports, hiking, work, and casual footwear.
- Material Development: Compares leather, mesh, membrane, and foam components.
4. User-Centric Design
- Touchscreen Workflow: Pre-loaded SATRA protocols with adjustable sweat rates (50–500 mL/hour).
- Self-Calibrating Sensors: Auto-zeroing for thermal/humidity channels.
5. Data Integrity
- 21 CFR Part 11 Compliance: Audit-ready electronic records with e-signatures.
- AI-Assisted Analytics: Machine learning identifies moisture migration patterns.
Product Features
- Advanced Sweat Simulation:
- Peristaltic pump delivers precision sweat volumes (0.01mL resolution).
- Heated foot model (32–45°C) with embedded thermal gradient mapping.
- Dynamic Airflow System:
- Variable-speed fan replicates walking airflow (0–5 m/s).
- 3D-printed air diffuser ensures laminar flow across shoe upper.
- Multi-Sensor Array:
- 16 thermal couples measure surface/interface temperatures.
- Capacitive humidity sensors track vapor transmission.
- Calibration & Safety:
- NIST-traceable thermal calibration with on-screen QR code verification.
- Over-temperature shutdown at 50°C.
- Software Suite:
- ShoeComfort Pro™: Real-time thermal maps and moisture diffusion modeling.
- CloudLab: Remote monitoring for global R&D teams.
