Introduction
Oral and axillary thermometers operate on the same principle, both utilizing the expansion and contraction of materials due to temperature changes to measure body temperature. They typically use either mercury or electronic sensors to detect temperature variations. Oral thermometers are primarily designed for measuring oral temperature, with a normal range generally between 36.3°C and 37.2°C, while the normal axillary (underarm) temperature range is between 36.1°C and 37°C.
Generally, an oral thermometer can be used to measure axillary (underarm) temperature. If discomfort occurs, prompt medical attention is recommended. Detailed explanation is as follows:

When using an oral thermometer to measure axillary temperature, the measurement method is essentially the same as when using a dedicated axillary thermometer. Place the probe or mercury end of the thermometer in the center of the armpit, let the arm hang naturally, hold the thermometer tightly, and ensure sufficient contact between the thermometer and the skin to obtain an accurate reading.
Regardless of the type of thermometer, it is important to ensure that the thermometer has been properly disinfected and is used correctly before measurement, to ensure accurate results. If the measured temperature is abnormal, it is recommended to retake the measurement or seek medical attention promptly.
