New Dimensions in the Measurement of Thermal Diffusivity and Conductivity – Fast, Simple, Economical

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.

Features of LFA 467 HyperFlash
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 patent-pending ZoomOptics system 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.
