✦ Synopsis

The resistance of a commercial Cernox (ceramicoxynitride) thermometer has been measured from 4.2 to 30 K in magnetic fields up to 15 T and compared to that of a carbon-glass thermometer. Throughout this field and temperature range, the maximum magnetic field-induced change in the zero-field calibration of the Cernox thermometer is less than 200 mK. This is a factor of two lower than that of the carbon-glass thermometer.

Furthermore, its sensitivity at room temperature is a factor of two higher.
