Benchtop High-Precision Material Thermal Conductivity Tester (Guarded Hot Plate Heat Flow Meter Method) is a high-precision instrument designed to measure thermal conductivity and thermal resistance of materials using the widely accepted guarded hot plate heat flow meter method. The instrument applies a stable temperature on one side of the sample, measures the heat flow transmitted to the cold side, and calculates thermal conductivity and thermal resistance automatically. Featuring imported sensors and advanced computer control, the system ensures high measurement accuracy, reliability, and excellent repeatability. It is particularly suitable for low thermal conductivity materials (accurate to 0.1 mW/m·K) and can be used to test plastics, rubber, insulation materials, aerogel panels, vacuum glass, and more. This instrument is widely applied in universities, research institutes, quality inspection agencies, and industrial enterprises.
Application
The tester is suitable for:
Plastics, rubber, and insulation materials
Aerogel panels and vacuum glass
Low thermal conductivity materials requiring high-precision measurement
Common applications include:
University and academic research: Material thermal property analysis
Industrial quality inspection: Ensuring material thermal performance
R&D laboratories: Testing new insulation or thermal management materials
Factory and production control: Material screening for thermal conductivity
Standards
The instrument complies with:
GB/T 10295-2008 – Steady-state thermal resistance and related characteristics of thermal insulation materials using the heat flow meter method
ASTM E1530 – Standard Test Method for Evaluating the Steady-State Thermal Transmission Properties of Materials
ASTM C518-04 – Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus
GB/T29313-201
