Abstract An instrument for measuring the radiation temperature of the ground or water surface with self-calibration function was developed. The design principle, specific structure, test procedure and final experimental results of the instrument were described. In order to verify the performance of the instrument, the emissivity measurement experiment of the calibration blackbody and the temperature stability test were carried out. The results show that the blackbody emissivity is higher than 0.996, and the temperature control stability is better than 0.04 K. The calibration of each temperature sensor was performed; The control and data acquisition procedures were completed; the radiation temperature measurement experiment of the prototype was carried out. Finally, the temperature range of the self-calibrated surface water meter infrared radiation thermometer is 223~333 K, and the temperature uncertainty is 0.2 K.
