Plate thermal conductivity tester

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

Application

Measures thermal conductivity of refractoryinsulation, 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.

Product Advantages

High-Temperature Precision: Operates up to 1200°C with ±1°C accuracy.

Multi-Sample Testing: Simultaneously tests 1–4 specimens.

Automated Control: Fully automatic operation for stable heat flow measurement.

Wide Thermal Range: Covers 0.03–2.00 W/(m·K) for diverse materials.

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.
