We present a design for a complex measuring device that enables its user to assess the parameters of power-generating thermoelectric modules (TEMs)(or bulk thermoelectric materials)under a wide range of temperatures(Tcold=25°Cto90°C,Thot<450°C) andmechanical loading(P=0 N to 104 N).The proposed instrument is able to monitor the temperature and electrical output of the TEM, the actual heat flow through the module, and its mechanical load, which can be varied during the measurement. Key components of our testing setup are (i) a measuring chamber where the TEM/material is compressed between thermally shielded heating blocks equipped with a mechanical loading system and water-cooled copper-based cooler, ii)an electrical load system,(iii)a type K thermocouple array connected to a data acquisition computer, and(iv) a thermostatic water-based cooling system with electronically controlled flow rate and temperature of cooling water.
