Pt‑40%Rh Versus Pt‑6%Rh Thermocouples: An emf‑Temperature Reference Function for the Temperature Range 0 °C to 1769 °C

Data for the associated paper, DOI https://doi.org/10.1007/s10765-021-02895-w The paper describes the metrological characterization of the highly stable Pt40%Rh/Pt-6%Rh thermocouples to determine their reference function in the temperature range between 0 °C and 1769 °C. The preparation of the Pt-40%Rh/Pt-6%Rh thermocouples is described, as well as the measurement procedures and the measurement results of comparison and fxed point measurements for the determination of the reference function with low uncertainties.
