Abstract： The calibration of digital thermometers using a fixed-point device can effectively improve the calibration uncertainty level. This paper describes the calibration method based on the fixed-point device and analyzed the uncertainty of the calibration results. The results show that the calibration of digital thermometers using fixed-point devices can effectively improve the level of uncertainty， which was conducive to the development of high-precision digital thermometer technology and the expansion of application scenarios.

Keywords： digital thermometer； fixed point device； uncertainty
