Temperature display instrument

The embodiment of the invention discloses a temperature display instrument, and the instrument comprises a temperature collection part which is used for collecting the real-time temperature of a to-be-measured shunt switch; a control part which is used for acquiring the real-time temperature output by the temperature collection part, comparing the real-time temperature with the storage temperature, and updating the storage temperature to the real-time temperature if the real-time temperature is greater than the storage temperature; and a display part used for displaying the storage temperature. According to the embodiment of the invention, the highest temperature in each time period of the whole day is recorded and displayed, so that the shunt load detection can be continuously carried out all day long, and the time for manually collecting data on site is more flexible compared with the prior art. Therefore, the accuracy of the shunt load detection result is improved, and the time limit of the detection perso
