A precision circuitry for the continuous and rapid measurement of absolute thermoelectric power (TEP) of metallic and semiconducting specimens under controlled conditions of temperature and pressure has been developed. The design of the system is centered around a fourth-order polynomial curve-fitting circuit which was primarily developed for the linearization of the nonlinear thermo-emf temperature characteristic. The variation with temperature of the relative TEP of the thermocouple and the absolute TEP of either of the constituents of the thermocouple, which are essential for the measurement of absolute TEP of the specimen, can also be simulated with this circuitry. The performance of the system is demonstrated by some typical data on the pressure-induced gamma - alpha transition in cerium.
