Laboratory for thermophysical properties and thermal analysis

The aim of our certified testing laboratory (EN ISO/IEC 17025:2005) is to support customers and project partners regarding analyzing and interpretation of thermal material properties or thermal processes.
Our thermophysical and thermal analysis methods enable to measure different solids, liquids and evolved gases as function of temperature, time and pressure conditions.
Moreover kinetic analysis and temperature field calculations based on experimental material data can be conducted.
