Thermal Conductivity Analyser
In view of vanishing primary energy resources and global warming, the thermo-physical properties of substances increasingly gain in importance. Knowledge of the specific heat is indispensable, above all for an economic energy use; thermal conductivity and thermal diffusivity are the most important parameters of new, more efficient working materials in the field of energy management, process engineering, biogene fuels and effective insulators for constructional energy saving. As fuels and insulators, renewable raw materials offer ecologic advantages. Their contribution to the protection of the environment and the climate as well as to the protection of finite fossil fuels still depends considerably on their thermo-physical properties which, until now, have been unknown in many cases.
The Transient Hot Bridge technique enables thermal conductivity, thermal diffusivity and specific heat measurements on various sample geometries and materials. This Linseis measuring instrument provides the three material properties simultaneously after just a few minutes time – regardless of whether you have used the patented sensor in a solid matter (incl. bulk material, gels, pastes) or in a liquid.
Here you can find a presentation about the Transient Hot Bridge.
