Shoe heat insulation meter -- sand bath
Standard
GB/T 20991: Determines thermal insulation of safety shoe soles under simulated hot surface exposure.
EN ISO 20344: European standard for personal protective equipment (PPE) footwear thermal resistance testing.
Product Advantages
1. Accredited Thermal Performance Analysis
Dual-Standard Compliance: Meets stringent Chinese and EU regulations for global market access.
Traceable Calibration: NIST-traceable temperature verification with certificate.
2. Realistic Testing Conditions
Granular Heat Transfer: Simulates contact with hot surfaces (e.g., asphalt, metal) via industrial-grade silica sand.
Steel Ball Simulant: Replicates foot pressure distribution inside the shoe.
3. Safety-First Design
Insulated Enclosure: Heat-resistant acrylic shield with interlock safety switches.
Emergency Cooldown: Auto-shutoff at 60°C surface temperature.
4. Precision Control
PID Temperature Regulation: ±0.5°C stability across 50–200°C range.
Fast Response Probes: K-type thermocouples with 0.1°C resolution.
5. User-Centric Workflow
Plug-and-Play Sensors: Pre-calibrated probes with color-coded connectors.
Intuitive Interface: 4.3” TFT display with real-time temperature curves.
