Thermal Conductivity Meter

The DR2 Plate Method Thermal Conductivity Tester operates on the principle of unidirectional steady-state heat transfer. When the upper and lower surfaces of a sample are maintained at different stable temperatures, it measures the heat flux through the sample's effective heat transfer area, along with the temperature difference between the two surfaces and the sample thickness, to calculate the thermal conductivity. Its core functionality lies in determining thermal conductivity by measuring the temperature difference across the sample, the heat flux, and the sample's geometric dimensions.

The Plate Method Thermal Conductivity Tester is a steady-state thermal conductivity instrument designed for building insulation materials, composite materials, multilayer materials, and porous materials, based on the protective plate method measurement principle. It offers high measurement accuracy and excellent temperature control stability, featuring automatic pressure application and measurement, as well as automatic thickness measurement, to accommodate experiments at various temperatures.
