New Dimensions in the Measurement of Thermal Diffusivity and Conductivity – Fast, Simple, Economical
Broadest temperature range available, from -100°C to 500°C
With a single instrument setup – that is, without having to swap out either the detector or the furnace – the LFA 467 HyperFlash® can carry out measurements from -100°C to 500°C. Coupled with the broadest range of accessories available on the market, the instrument opens the door to completely new dimensions in the determination of thermophysical properties.
Sample throughput up to 4 times higher due to sample holder for 16 samples
One unique advantage of the LFA 467 HyperFlash® is its ability to simultaneously measure up to 16 samples over the entire temperature range. This allows for maximum sample throughput with a minimum input of operational time and effort.
Refill systems are available for automatic refilling of the Dewar on both the detector and the furnace, allowing uninterrupted operation of the LFA system around the clock.
ZoomOptics for more precise measurement results without measurement errors
The patented ZoomOptics system (patent no.: DE 10 2012 106 955 B4 2014.04.03) optimizes the field of view of the detector, thus eliminating any influences caused by aperture stops. The result is a significant increase in the precision of the measurement results.
Ultra-fast recording of measurement data for thin samples (2 MHz)
Thin films and high-conductivity materials require a very high data acquisition rate for the precise recording of rapid temperature increases on a sample’s upper surface. The LFA 467 HyperFlash® offers a sampling rate of 2 MHz – an unprecedented value for LFA systems.

Data acquisition rate
Measuring range Thermal DiffusivityThermal diffusivity (a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature.thermal diffusivity:
0.01 mm2/s to 2000 mm2/s
Measuring range Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity:
< 0.1 W/(m*K) to 4000 W/(m*K)
6 mm to 25.4 mm diameter
0.01 mm to 6 mm thickness
Patented pulse mapping technique
for pulse length correction and improved cp determination
