Plate thermal conductivity tester

Application

Measures thermal conductivity of refractory insulation, ceramic fiber, textiles, boards, and bricks at elevated temperatures (200°C–1200°C). Ideal for manufacturers of heat-resistant materials, quality inspection agencies, universities, and R&D institutes.

Standards

• GB/T 17911-2006: Test methods for refractory ceramic fiber products.
• YB/T 4130-2005: Water flow plate method for thermal conductivity of refractories.
• ASTM C518
• IS0 8301
• DIN EN 12667

Product Advantages

1. High-Temperature Precision: Operates up to 1200°C with ±1°C accuracy.
2. Multi-Sample Testing: Simultaneously tests 1–4 specimens.
3. Automated Control: Fully automatic operation for stable heat flow measurement.
4. Wide Thermal Range: Covers 0.03–2.00 W/(m·K) for diverse materials.
5. Uniform Heating: Ensures temperature consistency in the sample chamber.

Product Features

• Testing Principle: Based on Fourier’s one-dimensional steady-state heat conduction, measuring heat transfer via water calorimetry.
• Key Components:
  • High-Temperature Furnace: Air-atmosphere heating up to 1200°C.
  • Calorimeter System: Central and shield flow meters (2.5–25 L/h).
  • Water Supply Unit: Maintains steady coolant flow (10–100 L/h).
• Sample Preparation: Dried at 110°C±5°C or processed per material standards.
