Thermal diffusivity (with a unit mm2/s) is the thermal conductivity divided by density and specific heat capacity at constant pressure while thermal conductivity is a measure of how easily one atom or molecule of a material accepts or gives away heat. Thermal diffusivity testing measures the rate of transfer of heat of a material from the hot end to the cold end.
Thermal Diffusivity is often measured with the flash method (LFA). It can also be measured with Hot Disc Transient Plane Source (TPS), Transient Hot Wire (THW) and Monotonic Heating (MMH). Our thermal diffusivity measurement methods cover a wide range of temperature and sample types. If you have any questions about these testing methods, please contact us and we will answer as quick as possible.
If you only need a limited number of thermal diffusivity tests, then our contract testing services are what you need. Request a quote today or contact us if you have any questions. We have a full-service thermal testing laboratory to accommodate your thermal diffusivity testing needs using the best thermal diffusivity testing methods available.
