ASTM D5470 Heat Flow Method Vacuum Type Thermal Conductivity Tester DRL-III-P Rubber Thermal Resistance Test Equipment

The DRL-III thermal conductivity tester is designed for precise measurement of thermal resistance in various materials including thin thermal conductors, solid electrical insulation materials, thermal conductivity silicone grease, resin, rubber, beryllium oxide porcelain, and alumina porcelain. It also measures contact thermal resistance at solid interfaces and material thermal conductivity.

• Testing solid sheet materials
• Measuring powder and paste materials using enclosed frame
• Thermal resistance curves under different pressures
• Multiple parameter measurement including thermal conductivity, thermal resistance, and contact thermal resistance

• MIL-I-49456A (insulation sheet, thermal conductivity resin, thermal conductivity glass fiber reinforced)
• GB5598-2015 (Beryllium oxide porcelain thermal conductivity determination method)
• ASTM D5470-2017 (thin thermal conductivity solid electrical insulation material heat transfer performance test standard)

• Automatic pressure and thickness measurement
• Computer-controlled operation with data printing output
• 6-point temperature gradient detection for improved accuracy
• Vacuum testing capability (0.1MPa) for precise environmental control
• Multiple test methods including thermal resistance, thermal conductivity, and contact thermal resistance

Widely used in colleges and universities, scientific research units, quality inspection departments, and material production facilities for thermal analysis and detection.
