A nickel carbon eutectic point was realized by a radiation thermometer for two geometrically different fixed point cells made by an optimized filling process. The process was based on monitoring the variation of the melting–freezing temperature difference as a function of the filling ratio of the cell. The integrity of construction and the filling endpoint could be confirmed by observing a clear convergence of the melting–freezing temperature difference as the filling ratio increases. From 14 sets of realizations with two different cells and two different spectral bands of the radiation thermometer, the eutectic temperature is determined to be 1328.73 °C with an expanded uncertainty of 0.22 °C (k = 2).
