Thermal Conductivity of Building Materials Apparatus Model TH 074

This experimental unit enables experiments to be performed on steady-state heat conduction in non-metallic materials such as polystyrene, PMMA, cork or plaster in accordance with DIN 52612.

Item Description

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. The measured values are transmitted directly to a PC via USB. The data acquisition software is included.
