Summary

THE PAPER PAYS ATTENTION TO STABILITY OF 10 TWO-LEAD INDUSTRIAL-GRADE 100 OHMS PLATINUM RESISTANCE THERMOMETERS USED IN THE TEMPERATURE RANGE FROM 77 TO 273 K. THE STATIC STABILITY WAS CHECKED BY STORING THE THERMOMETERS FOR ABOUT TWO YEARS, THE DYNAMIC STABILITY WAS TESTED BY CYCLING IN 25 CYCLES FROM ROOM TEMPERATURE TO THE TEMPERATURE OF LIQUID NITROGEN. THE STATIC INSTABILITY OF THE THERMOMETERS RANGED WITHIN + 2.5 TO + 7.7 MILLIK, ONLY ONE THERMOMETER SHOWED -2.5 K. THE DYNAMIC INSTABILITY RANGED WITHIN -5 TO -80 MILLIK, ONLY ONE THERMOMETER SHOWED + 35 MILLIK.
