The flat plate thermal conductivity meter, with a water bath constant-temp device and computer-controlled measurements, tests thermal conductivity of homogeneous plate-shaped materials like plastics, rubber, etc. It can also measure granular, bulk, and soft materials. It's widely used by heat-resistant/insulation material makers, quality inspection departments, and research institutions.

Application

The tester is suitable for high-temperature thermal conductivity testing in multiple fields:

Refractory and Insulation Materials: Evaluates ceramic fiber, refractory bricks, insulation boards, and high-temperature insulation materials.

Textiles and Composite Materials: Measures thermal properties of heat-resistant fabrics and composite plates.

Building Materials: Assesses the thermal performance of boards, bricks, and other construction materials.

Research & Development: Supports development of new heat-resistant or insulating materials, as well as quality control of existing products.

The apparatus provides accurate, reliable measurements at temperatures ranging from 200°C to 1200°C, supporting both laboratory research and industrial quality control.

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: Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus

IS0 8301:Thermal Insulation — Determination of Steady-State Thermal Resistance and Related Properties — Heat Flow Meter Apparatus

DIN EN 12667:Thermal Performance of Building Materials and Products - Determination of Thermal Resistance by Means of Guarded Hot Plate and Heat Flow Meter Methods - Products of High and Medium Thermal Resistance

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.
