Thermal Storage Coefficient Tester
This instrument features computer-based data acquisition, control, and data processing functions. Its key characteristics include a simple setup, high accuracy, and fast testing speed (a single test takes approximately 10 minutes). It simultaneously measures the thermal storage coefficient, thermal conductivity, thermal diffusivity, and specific heat of materials in a single test, and can buate thermal perbance under various moisture content conditions.
JGJ/T 12-2019 Technical Standard for Application of Lightweight Aggregate Concrete
GB/T 20473-2021 Building Thermal Insulation Mortar
Suitable for measuring the thermal storage coefficient, thermal conductivity, thermal diffusivity, and specific heat of homogeneous plate-shaped or powdered materials in both dry and varying moisture states.
Thermal conductivity range: 0.035–1.7 W/(m·K) (or 0.03–1.5 kcal/(m·h·°C))
Thermal storage coefficient range: 0.1–30 W/(m2·K)
Based on the principle of unsteady-state heat transfer, the instrument applies a brief heating pulse to the test material, inducing temperature variations. By solving the heat conduction differential equation using the observed temperature response, the material’s thermal storage coefficient, thermal conductivity, thermal diffusivity, and specific heat are calculated.
