Hot Disk TPS 3500
Hot Disk TPS 3500
"For testing the extreme" – the newly developed TPS 3500 is the answer to the current challenges in materials research, involving ever smaller (thinner) samples with extremely high thermal conductivity – complies with ISO Standard 22007-2.The TPS 3500 has been specially developed for measuring small, highly thermally conductive samples, such as those used in the electronics industry. It offers all the capabilities of the TPS 2500S, but also enables measurements on the smallest sample geometries thanks to even shorter measurement times. The system complies with ISO standard 22007-2.
Product Description
The new TPS 3500 Hot Disk System is the ideal system for determining the thermal conductivity, thermal diffusivity and heat capacity of small, highly thermally conductive samples. This enables the shortest measuring time of 0.1 seconds with the usual high accuracy with a measuring range for thermal conductivity of 0.005 to 1800 W/mK. This makes the TPS 3500 the ideal tool for R&E wherever the highest resolution is required.
The device works according to the so-called “Transient Plane Source” method and fulfils the ISO 22007-2 standard.
The hot disc technique is also known as the “Transient Plane Source” (TPS) technique. The method works dynamically in a transient manner and is therefore very fast. The flat sensor serves as a heat source and temperature sensor at the same time. For standard measurements, it is placed between two samples of identical material. The samples only need to have a flat surface, but can also have rough or porous surfaces. The effort required for sample preparation is therefore minimal.
In a standard measurement, the TPS 3500 determines the thermal conductivity, the thermal diffusivity and the heat capacity (per unit volume) of the measured sample. Typical samples are solids, powders, bulk materials, foams and liquids.
The optional measuring modules available for the TPS 3500S and the possibility of extremely short measuring times of up to 0.1 seconds extend the range of applications, especially for extremely good thermal conductors and small available dimensions. This applies above all to the application area of electronics with increasingly better thermally conductive materials.
