Abstract
To reduce the uncertainty of thermal equilibrium between samples and thermometers, the thermometric fixed points of the superconductive phase transitions of lead and indium are measured by the static method, which have been traditionally measured by scanning temperatures near the phase transitions. The phase transition widths are found to be within 1mK even in the case of the static method. The static method may be suitable to calibrate thermometers at the superconductive phase transitions and to estimeate the uncertainties.
