Shoe heat insulation testing machine -- 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.
