Product Advantages
- Precision Thermal Engineering
- Uniform Heat Distribution: 150±5°C standard temperature with ±2°C gradient across 4 helmets.
- Rapid Heating: Reaches 200°C in <45 minutes (10°C/min ramp rate).
- Multi-Sample Efficiency
- 4-Helmet Capacity: Simultaneously pre-treats samples for accelerated testing.
- Independent Control: Adjusts time/temperature per helmet position.
- Biofidelic Headform Design
- Aluminum Alloy Molds: Hollow 1.5mm-thick headforms with 50±2°C internal temperature.
- Anatomical Accuracy: Replicates human head thermal conductivity (0.48 W/m·K).
- Safety & Compliance
- Over-temperature protection: Auto-shutdown at 210°C.
- Audit-ready reporting: Generates GB/T 2812-2019-compliant certificates.
- User-Centric Operation
- 7" Touchscreen: Intuitive interface with multi-language support (EN/DE/ZH/ES/FR).
- Quick-swap headforms: Fits EN 960 S/M/L sizes in seconds.
