Testing Thermal Conductivity

Hot Disk AB develops and provides equipment for measuring and testing thermal conductivity, thermal diffusivity and specific heat capacity. With our equipment, testing thermal properties is easy, fast and non-destructive.

World-leading Thermal Conductivity Analysers

Test Thermal Conductivity, Thermal Diffusivity and Specific Heat of most material types in a single measurement! This is possible with the absolute Hot Disk method, with no need for repeated calibrations or use of standard samples. This flexible 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!

Near-field radiation on a nano-scale, studied with the Hot Disk TPS 2500 S.

The first ever transient measurements of Super-Planckian near-field radiative heat transfer has been performed utilizing a Hot Disk TPS 2500 S instrument. The experiments were performed in a collaboration between five laboratories, in four different counties, involving in total eight scientists. The results of these measurements, which closely follow the theoretical expectations but deviate substantially from earlier (less accurate) steady-state measurements, are published in Nature Scientific Reports.

TPS 3500

For testing the extreme

When samples are small and high-conducting, the Hot Disk TPS 3500 is the ideal instrument for testing their thermal conductivity, thermal diffusivity and specific heat. The capabilities of TPS 3500 go well beyond that of any other Hot Disk instrument to date, while retaining the documented precision of all TPS thermal conductivity meters. It meets ISO 22007-2.

TPS 2500 S

The benchmark instrument

The Hot Disk TPS 2500 S is the core instrument in the system portfolio of Hot Disk AB. This general-purpose R&D thermal conductivity meter is designed for precision analysis of thermal transport properties of materials of any type. It is a capital research instrument and meets ISO 22007-2.

TPS 2200

For day-to-day testing

The Hot Disk TPS 2200 is an affordable option when performance and price are both in consideration. It tackles a good range of sample types and it is suitable for day-to-day testing in any laboratory with a focus on material science. The TPS 2200 meets ISO 22007-2.

TPS 1500

For heavy-duty testing

The affordable Hot Disk TPS 1500 is the ideal thermal conductivity meter for testing building materials, insulation materials or any other type of large bulk samples. The TPS 1500 shares the sterling quality, robustness and operative simplicity of the benchmark TPS 2500 S and meets ISO Standard 22007-2.

TPS 500 (S)

For the small-scale lab

The Hot Disk TPS 500 Thermal Constants Analyser rapidly and accurately measures the thermal conductivity, thermal diffusivity and specific heat capacity of a wide range of materials and is therefore an excellent step-in Thermal Conductivity Meter. The TPS 500 S model adds powerful new features to the 500-series.

Hot Disk M1

For the slim budget

The Hot Disk M1 is a basic Thermal Conductivity Meter which nevertheless offers high accuracy and measurement repeatability. With the M1, solids, powders and pastes in the thermal conductivity range of 0.03 to 40 W/m/K are readily tested.
