A simple, economically viable and precise thermopower measurement techniques have been presented in this paper. Continuous data acquisition and simultaneous control of the instruments are achieved by using LabVIEW software. Set-up is built to measure thermopower of the low temperature thermoelectric material down to 10K. A LabVIEW program is developed to collect thermopower data of few μV/K to few hundred μV/K. Thermal stabilization and simple calculations are incorporated to avoid the spurious thermopower. Thermopower measurements, carried out in this set-up are published in reputed journals.
