Rock Thermal Conductivity Tester
The instrument measures thermal conductivity and thermal resistance by transient heat-flow and longitudinal heat-flow methods from 0.015–100 W/(m·K). It uses automatic loading, pressure control, computer acquisition, and a controlled cold end for specimens tested from room temperature to 300 °C.

Product Description
The vertical apparatus applies adjustable loading force and uses temperature measurements at lateral and axial positions to determine radial and longitudinal heat-transfer behavior. An auxiliary heater can be installed at the opposite end to derive radial heat transfer from the lateral temperature distribution over heating time.
The system includes a constant-temperature water bath for the cold end, touchscreen control, and computer test software.
