Thermal Conductivity Device ASTM C518 ISO 8301 for Thermal Insulation Materials
The thermal conductivity measured by the high-temperature resistant material thermal conductivity tester refers to the amount of heat transferred per unit time along the heat flow direction through a unit area of the material under a unit temperature gradient.
Based on the fundamental principle of Fourier one-dimensional plate steady-state heat conduction, this device measures the amount of heat transferred longitudinally through the hot surface of the sample to the cold surface and then absorbed by the water flowing through the central calorimeter per unit time in a one-dimensional temperature field during steady-state operation.
