DRE-III ISO 22007 Multi-function Fast Thermal Conductivity Tester
Product Description
The DRE-III multi-function fast thermal conductivity tester utilizes the transient plane heat source method (TPS technology) with Hot Disk probe for accurate thermal property measurements.
Key Advantages
- Direct heat propagation measurement saves significant time
- Unaffected by contact thermal resistance issues common in static methods
- Minimal sample preparation required - only relatively flat surfaces needed for solids
- Custom test schemes and mathematical models for different material types
- Wide measurement range and fast testing speed
Standards Compliance: ISO 22007-2:2015, GB/T32064-2015
Test Material Compatibility
Metals, alloys, graphite, thermal conductive silicone grease, silica gel, silicone rubber, ceramics, geotechnical materials, rocks, polymers, paper, fabrics, foam plastics, concrete, composite boards, paper honeycomb boards, and other solids, powders, liquids, pastes, coatings, films, insulation materials, and anisotropic materials.
