  In this work, we report the fabrication of a high temperature measurement
setup to measure Figure of merit (ZT). This setup facilitates the simultaneous
measurement of Seebeck coefficient ({\alpha}), thermal conductivity (\kappa),
and electrical resistivity (\rho) required to calculate ZT. Measurement of
temperature, as well as voltages using same thermocouples, simplified the
design of the setup by minimizing sensors and wires. Limited components used in
the sample holder further simplify the design and make it small in size and
lightweight. The dedicated thin heater is made, which minimizes the heat loss.
Further, low heat loss is achieved by optimizing the insulator dimension. To
measure power delivered to the heater, 4-wire technique is used. Low cost and
commonly available materials used in the fabrication of various components make
it more accessible to the user as any parts can be easily replaced in case of
any damage occurs. A dedicated program is built in the Python programming
language to automate the whole measurement process. p-type Bi0.36Sb1.45Te3
sample is used to calibrate this measurement setup. The data collected are
found to be in good agreement with the reported data.
