Hot Disk TPS 2200

Product Description

The Hot Disk System TPS 2200 is a universal tool for the R&E. sector.

Only with very small dimensions or extremely good thermal conductivity properties of the samples is the application range of the TPS 2200 limited – in this case the TPS 2500S and TPS 3500 are used. The measuring range of the TPS 2200 for lambda extends from 0.01 to 500 W/mK, depending on the choice of temperature control, it can be used in a range from -50 to 750.

The TPS 2200 works according to the so-called “Transient Plane Source” method and fulfils the ISO standard 22007-2.

Hot disc technology is also referred to as “Transient Plane Source” (TPS) technology. 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 with the TPS 2200, it is placed between two samples of identical material. The samples only need to have a flat surface, but may have rough or porous surfaces. The effort required for sample preparation is therefore minimal.

Almost all optional measurement modules/software packages are already available for the TPS 2200.
The anisotropy module enables the determination of thermal and thermal diffusivity in radial and axial direction. Thin films and foils or even coatings can be characterised with the thin film module. The cp module enables high-precision cp measurements. The slab module was developed for measurements on highly thermally conductive metal sheets etc. The low-density/highly insulating module is used especially for materials with low density and very low thermal conductivity, such as aerogels.
