The first carbon-13 shift thermometer for the temperature range of 100 -300 K is based on the very rapid equilibration of a pair of semibullvalene valence tautomers. The temperature dependence of the equilibrium constant is reflected in strongly temperature-dependent shift differences โฌโฆ between ave

GaAs diode thermometers have been demonstrated to be reliable and reproducible transducers in both the liquid nitrogen and helium range, but so far no equation has been available for interpolating the voltege-temperature characteristic, at constant current, with an accuracy better than 1 K.
We describe how a simple two-point calibration of a platinum resistance thermometer can be used to deduce the resistance-temperature relationship in the range 4.2 K ~ T <~ 273 K. This relationship is established by comparing the unknown thermometer to two carefully calibrated platinum resistance the
