Thermal Conductivity

Thermal conductivity and diffusivity are the most important thermophysical material parameters for the description of the heat transport properties of a material or component. For the precise measurement of thermophysical properties like the thermal diffusivity, the Laser Flash technique (LFA) has proven itself as a fast, versatile and precise absolute method. NETZSCH offers four LFA models, covering the entire spectrum of materials and temperatures.

Based on an absolute measurement method, the GHP 456 Titan is the ideal instrument for the determination of thermal conductivity of insulations.

The thermal conductivity as another significant thermophysical property is determined by means of heat flow meters (HFM) with the plate method for insulators.
