  In this work, we report the fabrication of fully automated experimental setup
for high temperature Seebeck coefficient ({\alpha}) measurement. The K-type
thermocouples are used to measure the average temperature of the sample and
Seebeck voltage across it. The temperature dependence of the Seebeck
coefficients of the thermocouple and its negative leg is taken care by using
the integration method. Steady state based differential technique is used for
{\alpha} measurement. Use of limited component and thin heater simplify the
sample holder design and minimize the heat loss. The power supplied to the
heater decides the temperature difference across the sample and the measurement
is carried out by achieving the steady state. The LabVIEW based program is
built to automize the whole measurement process. The complete setup is
fabricated by using commonly available materials in the market. This instrument
is standardized for materials with a wide range of {\alpha} and for the wide
range of {\Delta}T across the specimen. For this purpose, high temperature
measurement of {\alpha} of iron, constantan, bismuth, and Bi_0.36 Sb_1.45 Te_3
samples are carried out and data obtained from these samples are found to be in
good agreement with the reported data.
