The cost of thermal conductivity testing is highly dependent on the number of samples to be tested and method of testing required. Contact us to request a quote. We have a full-service thermal testing laboratory to accommodate your thermal conductivity testing needs using the best thermal conductivity measuring methods available.
Thermal conductivity and heat conductivity are often used interchangeably, but there is a subtle distinction between the two terms. Thermal conductivity refers to a material’s ability to conduct heat, quantifying how efficiently heat is transferred through the material. On the other hand, heat conductivity can be considered as the actual process of heat transfer itself, regardless of the material. It encompasses conduction, convection, and radiation, which collectively contribute to the overall heat transfer.
While thermal conductivity focuses on the material’s specific property, heat conductivity is a broader term encompassing the transfer of heat energy in general. In practice, however, these terms are often used to describe the same property or process.
