DESCRIPTION

This experimental unit enables experiments to be performed on steady-state heat conduction in non-metallic materials such as polystyrene, PMMA, cork or plaster. Specimen sheets are placed between a heater plate and a water-cooled plate. A clamping device ensures that the clamping pressure and thermal contact are reproducible.

A special sensor measures the heat flux. Electronic controllers keep the temperatures of the heater plate and cooling plate constant within close limits.

Experiments

• Determination of the thermal conductivity λ of different materials
• Determination of the thermal resistance
• Thermal conductivity λ of several specimens connected in series (up to a thickness of 50mm)
