WL 376 Thermal Conductivity of Building Materials Show data sheet (pdf file) Print page
WL 376 - A product from the GUNT 2E range
Technical 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 in accordance with DIN 52612. 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.


Learning Objectives / Experiments
- determination of the thermal conductivity of different
- determination of the thermal resistance
- thermal conductivity of several specimens
  connected in series (up to a thickness of 50mm)

* Heat conduction in non-metallic materials1
* Material thickness or combinations up to a

  thickness of 50mm can be used
