I am looking for methods of measuring of the Seebeck Coefficient or devices alternative to Netzsch SBA 458 Nemesis. It will be great if the simultanous analysis of Seebeck Coefficient and electrical conductivity would be possible.
There are other commercial systems available for the simultaneous measurement of Seebeck and resistivity at high temperature, including typically ulvac zem3, linseis LSR-3, Ozawa Science RZ200li (...)
Many papers have also been published in the literature dealing with lab-made systems, so if you want to build one you can finid various design possibilities.
There are significnt differences between Seebeck systems on the market (setup, robustness, accuracy). Netzsch lab performs demo measurements free of charge.
