The stability at 20 K of five industrial-type platinum–cobalt resistance thermometers on thermal cycling has been studied together with their resistance-temperature characteristics between 1 and 27 K and their self-heating. The stability at 20 K on cycling between room temperature and 20 K is of the order of 10 mK and on cycling between 100 and 20 K is a few mK. Differences in the resistance-temperature relationships of the thermometers are very small, but the self-heating effects are relatively large, particularly below 4 K.
