โฆ Synopsis
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 thermometers. This technique produces an accuracy of (0. 1 -0.3) K. This accuracy should be adequate for many engineering applications.
