Transition temperatures of superconductive fixed points are extremely sensitive to ambient magnetic fields. Careful magnetic shielding, either active or passive, is required to obtain the standard zero-field condition. Application of an open shield simplifies the task by reducing the requirement of
Apparatus is described for using the melting point of mercury and the triple point of carbon dioxide as auxiliary fixed points for the calibration of platinum thermometers. The repfoducibilities of the points were respectively 0.0005 and 0.0002 degree.
