The LFA 717 HyperFlash® is a state-of-the-art instrument designed to accurately measure the thermal diffusivity of various materials. With its advanced calculation models, it is at the forefront of scientific innovation, ensuring accurate results essential for materials analysis.
- Broad sample range: The LFA 717 HyperFlash® can accommodate a wide range of sample materials, including both round and square-shaped specimens. It features an automatic sample changer that can handle up to 16 samples simultaneously, increasing laboratory efficiency.
- Flexible temperature control: The instrument offers remarkable flexibility in selecting the measurement range up to 500°C. Using liquid nitrogen, it can analyze samples at temperatures as low as -100°C. In addition, a compressed air unit allows sub-ambient measurements down to 0°C. The integrated evacuation system permits measurements in defined atmospheres.
- Advanced corrections specifically for thin or highly conductive samples: The latest version of our analysis software introduces an enhanced analysis pulse correction feature designed for high-precision applications where exceptional time resolution is critical. This enhancement is particularly beneficial when analyzing thin or highly conductive samples, and in situations where the light pulse coincides with the thermal response of the sample.

Laser Flash technique over the broadest temperature range
Thermal conductivity and thermal diffusivity 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 precision and reproducibility, short measurement times, variable sample holders and defined atmospheres 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 (DSC 404 F1 Pegasus®) and density (DIL 402 C) data are used to calculate the thermal conductivity.
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.... Read More |
