A Quarter Century of Testing Thermal Conductivity

Since 1995, Hot Disk AB develops and markets unique instruments measuring and testing thermal conductivity, thermal diffusivity and specific heat capacity. With our famed instruments, testing thermal properties is easy, fast and non-destructive.

World-Leading ISO-Standardised Thermal Conductivity Instruments

Reliably test Thermal Conductivity, Thermal Diffusivity and Specific Heat of solids, liquids, powders, and pastes in a single measurement! This is made easy with Hot Disk instruments. They integrate the absolute Hot Disk (Transient Plane Source, TPS) method, invented and developed in-house, with no need for repeated calibrations or use of standard samples. This flexible ISO-standardised (ISO 22007-2) method merely requires one or two pieces of the sample in question to test, each with no more than one flat surface where the sensor can be applied. There is no need for fixed geometries, contact agents or surface modifications.

Test your samples as they are – with a completely non-destructive method!

In-depth information on the method is found here.
