Abstract
A temperature calibration method for an ear thermometer with a probe cover is provided. The temperature calibration method includes: providing the ear thermometer with the probe cover, the ear thermometer including a plurality of activation elements which are configured to sense an infrared transmittance of the probe cover to obtain a measured transmittance value; using the ear thermometer to measure an object to be tested to obtain an uncalibrated temperature; obtaining an infrared radiation energy emitted by the object to be tested, according to the uncalibrated temperature, the measured transmittance value, a preset transmittance value, and a radiation energy measurement formula; and calibrating the uncalibrated temperature to a calibrated temperature, according to a temperature calibration function.
