LSR – Constantan – Seebeck coefficient – Thermoelectric properties

Measurement of constantan reference sample – Absolute Seebeck Coefficient

Bismuth telluride is the only NIST-certified reference material for the Seebeck coefficient. But it can be used only up to a maximum temperature of 120°C. Constantan can be used up to 800°C and therefore be used as a high temperature calibration material.

In contrast to the Bi2Te3 reference sample provided by NIST (SRM 3451)™, which is only useable in the low temperature range up to 390 K, our constantan reference sample can be used as a high temperature reference sample up to 800°C. The measurement shows a typical result for the Seebeck coefficient and the electric resistivity which fit perfectly in the specified tolerances.
