This paper presented the investigations of a commercial rhodium-iron resistance thermometer in cryogenic temperature. The two point's calibration was carried out in room temperature and liquid nitrogen temperature respectively, the test results proved the resistance-temperature formula which was provided by manufacturer. In addition, the thermal cycling test was done continuously for three times. Before the thermal cycling test, the temperature stability of the sensor in 77.4K is below 20mK, while that after the test is below 30mK, both results fulfill the requirement of practical application. All the test results show that, this rhodium-iron thermometer works reliably and stably in cryogenic temperature, that can provide some basis for its further application in superconducting magnet system.
