Which thermometer is characterized as a hand-held device for temperature measurement?

The tympanic thermometer is designed specifically for quick and easy measurement of body temperature by being inserted into the ear. Its hand-held nature makes it highly convenient for both medical professionals and non-professionals, allowing for rapid readings in a variety of settings, such as at home or in clinical environments.

Other types of thermometers also serve specific purposes, but they may not emphasize the hand-held feature as distinctly as the tympanic type. For instance, electronic thermometers can come in various forms, but many are not exclusively hand-held and can also be stationary. Mercury and glass thermometers typically require more careful handling and are often not designed for quick, casual use. Therefore, the tympanic thermometer stands out as a practical and user-friendly option that meets the criteria of being a hand-held device for temperature measurement.
