You should leave a mercury thermometer in place for about 3 minutes to ensure accurate reading. Make sure the thermometer is at the correct position under the tongue, armpit, or rectum, depending on the type of thermometer being used. Always follow the manufacturer's guidelines for accurate temperature measurement.
You should place the thermometer under your tongue for an accurate oral temperature reading.
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.
An axillary thermometer should be left in place for about 3-5 minutes to ensure an accurate reading.
You should place is along the wall.
Out of the hands of children, in a place protected from mechanical shock and away from extremes of temperature that could exceed the range of the thermometer.
To dispose of a digital thermometer, remove the battery and recycle it separately according to local guidelines. Place the remaining parts of the thermometer in the trash, unless your area has specific electronic recycling programs. Be sure to follow any specific disposal instructions provided by the manufacturer.

When using a digital thermometer under the arm (axillary), it typically needs to be left in place for about 5 to 10 minutes for an accurate reading. Ensure the thermometer is positioned correctly and the armpit is dry, as moisture can affect the reading. For the most precise results, consider using an oral or rectal thermometer, as axillary readings can be less reliable.
To check if a thermometer works properly, you can place it in ice water and it should read 0 degrees Celsius (32 degrees Fahrenheit). Alternatively, you can place it in boiling water and it should read 100 degrees Celsius (212 degrees Fahrenheit) at sea level. If the thermometer readings are within the expected ranges, it is likely working properly.
