LFA 457 MicroFlash
Our LFA 457 can measure thermal diffusivity of bulk samples from room temperature to 1000 °C under different atmospheres (Ar, air, N2, and O2). With sample´s density and heat capacity, you will be able to obtain the sample´s thermal conductivity.
The measurement principle can be obtained from the original literatures: Parker et al [1] and Cowan et al [2].
