We describe the design, construction, calibration and use of a near-infrared thermodynamic radiation thermometer to measure blackbodies from 400 K to 1300 K. The motivation for this work is the pending redefinition of the kelvin and the need for direct, thermodynamic temperature measurements of the fixed-point blackbodies presently used in the realization(More)
The precision blackbody sources developed at the All-Russian Institute for Optical and Physical Measurements (Moscow, Russia) and their characteristics are analyzed. The precision high-temperature graphite blackbody BB22p, large-area high-temperature pyrolytic graphite blackbody BB3200pg, middle-temperature graphite blackbody BB2000, low-temperature(More)
The thermodynamic temperature of the point of inflection of the melting transition of Re-C, Pt-C and Co-C eutectics has been determined to be 2747.84 ± 0.35 K, 2011.43 ± 0.18 K and 1597.39 ± 0.13 K, respectively, and the thermodynamic temperature of the freezing transition of Cu has been determined to be 1357.80 ± 0.08 K, where the ± symbol represents 95%(More)
