Thermal Storage Coefficient Meter Thermal Conductivity Tester High Accuracy Thermophysical Coefficient Test Machine
Thermal Storage Coefficient Meter Thermal Conductivity Tester High Accuracy Thermophysical Coefficient Test Machine
Product Introduction
This thermal storage coefficient meter is primarily used to measure the thermal conductivity, thermal storage coefficient, specific heat, and thermal diffusivity of lightweight aggregate concrete, homogeneous slabs, lightweight aggregate concrete, colloidal, powdered, and granular materials, both dry and at varying moisture levels. It can simultaneously measure and calculate various thermophysical coefficients under both dry and equilibrium moisture content conditions in a single test.
The thermal storage coefficient meter offers simple operation, high accuracy, and fast testing speed (a single test takes approximately ten minutes). Based on the principle of unsteady heat conduction, it briefly heats the test material, causing the material's temperature to change. Based on the characteristics of this temperature change, the thermal storage coefficient, thermal conductivity, thermal diffusivity, and specific heat of the test material can be calculated by solving the heat conduction differential equation.
