A Quarter Century of Testing Thermal Conductivity

Since 1995, Hot Disk AB develops and markets unique instruments measuring and testing Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity 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, Thermal Effusivity and Specific Heat Capacity 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.

TPS 3500

For testing the extreme

The Hot Disk TPS 3500 is the state-of-the-art instrument for testing the Thermal Conductivity, Thermal Diffusivity, Thermal Effusivity and Specific Heat Capacity of tiny, highly thermal conducting samples. The capabilities of the TPS 3500 go well beyond that of any other available instrument to date – Thermal Conductivity ranging from 0.005 to 1800 W/m/K, tackling 10-micrometer-thick slab samples, and accommodating temperatures from cryogenic to 1000ºC. It has also the unique ability to analyse the anisotropic thermal transport properties of both uniaxial and biaxial materials, by use of specialized Hot Strip sensors in the latter case. The TPS 3500 meets ISO 22007-2 and is CE marked.

TPS 1000

For cost-effective quality assurance

The Hot Disk® TPS 1000 is a powerful instrument for QC testing, measuring Thermal Transport Properties at very high precision. The TPS 1000 is scalable, where in its most basic configuration it functions primarily as a price-attractive simple Thermal Conductivity meter for 1D (through-plane) testing. Yet the TPS 1000 can also be used as a dedicated Specific Heat Capacity meter. In an upgraded configuration, the instrument can also be used as an advanced Thermal Conductivity, Thermal Diffusivity, and Thermal Effusivity meter, with performance and capability close to our TPS 2200 laboratory instrument. In other words tackles millimeter-thick bulk samples, measures Thermal Conductivity from 0.01 to 500 W/m/K, handles a temperature range from -100 °C to 750 °C, and be used to analyse the anisotropic thermal transport properties of uniaxial materials. The TPS 1000 meets ISO 22007-2 and is CE marked.
