The SBA 458 Nemesis® is heralded for its unique measurement setup, which accomodates more sample geometries than usually for this technique. Measurements can be carried out at temperatures up to 1100°C.
Changing samples is accomplished quickly and easily by hand, without any tools. By using sheathed thermocouples sticking of the sample to the electrodes is avoided.
The SBA 458 Nemesis® has two heavy systems that are employed in an alternating manner for each temperature step. Deviations from linearity and hysteresis due to inaccurate measurement can be immediately observed before and during the measurement.
The thermocouples are firmly anchored and are immobilized during the measurements by a defined contact force resulting from the mass and the cold spring. Sheathing of the thermocouples prevents diffusion from cementing them to the sample.

The software is based on Windows 7, 64 bit. It fully controls the measurements, which are performed at each specified temperature interval. The software allows for easy operation and control of the data.
The resistance (U-I plot) and quality check (Seebeck) functions are integrated. The measurement data can be easily exported.
