Thermal analyzer LFA 427

Thermal conductivity and thermal diffusivitv are the most important thermophysical material parameters for characterizing the thermal transport properties of a material or component. The Laser Flash technique is currently the most widely accepted method for precise measurement of the thermal diffusivity and the LFA 427 is the number one instrument on the world market. High précision and reproducibility, short measurement times, variable sample holders and defined atmosphères are outstanding features of LFA measurements over the entire application range from -120°C to 2800°C. A special version with a pyrometer allows measurements from room temperature to 2800°C. The Thermal conductivity of disk-shaped samples of ceramic, glass, metals, melts and liquids, powders, fibers and multi-layer materials ranging from vacuum insulation panels to diamonds is measured with equal speed and accuracy. The temperature-dependent measured thermal diffusivity value along with the corresponding specific heat. The laser power, pulse width, gas and vacuum are variable over a wide range, making it possible to set the optimum measurement conditions for the very different sample properties. The LFA 427 is the most powerful and versatile LFA system for research and development as well as all applications involving characterization of standard and high-performance materials in automobile manufacturing, aeronautics, astronautics and energy technology.
