Description

Digital thermometers provide clear numeric readings that are easier to interpret than an analog scale. They use electronic heat sensors or infrared rays to record body temperature.

Medical thermometers and temperature screening devices measure body temperature to help detect infection and illness or monitor treatment and recovery. Oral thermometers are the most commonly used type of thermometer. They provide a baseline of comparison for other temperature-taking methods. Rectal thermometers and ear thermometers give readings that are 0.5°F (0.3°C) to 1°F (0.6°C) higher than oral thermometers. They are primarily used to take the temperature of infants and young children. Noncontact infrared thermometers measure forehead temperature without touching the skin.
