Thermometer
Mercury-containing glass thermometers are no longer recommended
because of safety concerns. If you have one in your home, consider replacing it
with a digital electronic thermometer.
Digital electronic thermometers are accurate, easy to read, and
durable. Temperature strips are very convenient and safe but are not as
accurate as digital thermometers and should only be used to measure armpit
(axillary) temperature. They are inaccurate when used on the forehead.
Thermometers that measure the temperature in the ear are fast, easy to use, and
quite accurate, but they are expensive.
Rectal thermometers with enlarged bulbs are helpful for children
younger than 6 or anyone who cannot hold an oral thermometer in his or her
mouth. For more information on how to take a temperature, see the topic
Body Temperature.
