High-Precision Material Thermal Conductivity Tester (Guarded Hot Plate Heat Flow Meter Method) is a fully automated thermal property testing system designed for accurate measurement of thermal conductivity and thermal resistance using the internationally recognized heat flow meter principle. The instrument applies a stable controlled temperature to one side of the specimen, allowing heat to transfer through the material to a cooled surface, while the transmitted heat flux is precisely measured to calculate thermal conductivity and thermal resistance. Equipped with imported sensors and computer-based control and data processing, the system delivers high accuracy, strong reliability, and excellent repeatability, especially for low thermal conductivity materials.
Application
TheHigh-Precision Material Thermal Conductivity Tester is suitable for steady-state thermal performance evaluation of materials with low to medium thermal conductivity, including:
Thermal insulation materials
Plastics and polymer-based materials
Rubber and elastomer materials
Aerogel panels and advanced insulation boards
Vacuum glass and building energy-saving materials
Solid materials and powder materials (with appropriate sample configuration)
The instrument is widely used in universities, research institutes, quality inspection laboratories, and industrial material testing facilities for thermal conductivity and thermal resistance analysis.
Standards
The instrument is designed and operated in accordance with the following international and national standards:
GB/T 10295-2008
Thermal insulation — Determination of steady-state thermal resistance and related properties — Heat flow meter method
ASTM E1530
Standard Test Method for Evaluating the Resistance to Thermal Transmission of Materials by the Guarded Heat Flow Meter Technique
ASTM C518-04
Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus
