Frequently Asked Questions on Digital Thermometers


On what body parts can digital thermometers be used?

Digital thermometers can record body temperatures from the mouth, armpit or rectum often in less then a minute.

Who can use digital thermometers?

A digital thermometer is appropriate for newborns, infants, children and adults.

What are the types of digital thermometers available?

Types of digital Thermometers include:

  • Digital ear thermometers - Also called tympanic thermometers, use an infrared ray to measure the temperature inside the ear canal.
  • Digital pacifier thermometers - Can be used only if the patient uses the pacifier.
  • Temporal artery thermometers - Often sold as forehead thermometers, use an infrared scanner to measure the temperature of the temporal artery in the forehead.
  • Digital thermometers - Regular digital thermometers use electronic heat sensors to record body temperature.
How accurate are thermometer measurements?

An accuracy of +/-0.1°C can be considered state of the art for High Grade thermometers. By correctly applying a thermometer, the accuracy can be significantly increased. Inaccuracy in human body temperature measurements, which depends on the measurement location and time, are due to physiological changes and are not due to thermometer malfunction.
