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.

There are many types of household thermometers, with the most common being mercury thermometers. The freezing point of mercury is minus 39 degrees, and its highest boiling point can reach 356 degrees, so its measurement range is relatively wide. In addition, there are some electronic thermometers that have higher accuracy, faster reaction speed, and simpler operation.
