Abstract
A thin-film platinum resistance thermometer (SDT101A, Tama Electric Work Company), which is available commercially, has useful characteristics for thermometry in the range of 20 to 300K and in high magnetic fields up to 5T. The Z function-table of this platinum resistance thermometer (PRT) was obtained experimentally. We comfirmed a possibility of the two point calibration with a precision of ±0.1K above 30K.The magnetoresistance of this PRT at 30K is about 1.5% for a magnetic field of 5T, whose value is one order of magnitude smaller than that of a precision type PRT.
