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.
