Home thermometer armpit measurement method: Take a suitable position, lie flat or sit. Unbutton the clothes, dry the sweat in the armpits, and place the mercury end of the thermometer deep in the armpits to tightly adhere to the skin. Bend your arm over your chest, take it out 10 minutes later, wipe it clean with a 75% alcohol cotton ball, and read the value. During the measurement period, it is important to note that if there is sweat under the armpit, it must be wiped dry before measuring; If the armpit is loosened before the measurement time is up, it needs to be re measured and the time needs to be recalculated.

When using a household thermometer correctly, ensure that it is clean and dry, and check for any damage. For a mercury thermometer, you should grab the end without a metal end, vigorously shake it a few times, and swing the mercury back to the head of the thermometer, so that the mercury scale is below 35 ℃. For electronic thermometers, it is necessary to check if the battery is charged, as insufficient power can affect the measurement results.
