Summary

THE CHARACTERISTICS OF 12 INDUSTRIAL-GRADE AND 1 PRECISION PLATINUM RESISTANCE THERMOMETERS FOR TEMPERATURES FROM 66 TO 300 K AND IN MAGNETIC FIELDS UP TO 19 T ARE DESCRIBED. THE RESULTS FROM THE 13 MODELS FROM 9 SUPPLIERS ARE COMBINED TO PRODUCE MEAN VALUES THAT MAY BE USED TO CORRECT ANY OF THOSE THERMOMETERS FOR EFFECTS OF A MAGNETIC FIELD PARALLEL TO ITS LONG AXIS. THE CORRECTABILITY ERROR AT 19 T IS LESS THAN MORE OR LESS 0.3% BETWEEN 66 AND 110 K AND LESS THAN MORE OR LESS 0.1% ABOVE 110 K. MAGNETORESISTANCE DATA FOR RHODIUM-IRON AND GOLD-MANGANESE RESISTANCE THERMOMETERS ARE ALSO PRESENTED.
