Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The Transient plane source (TPS) method is used to test absolute thermal conductivity, thermal diffusivity and specific heat of solids, liquids, pastes and powders. Using the interactive demonstration below, you can learn how to make a measurement.
