1. Overview
Infrared Thermometer measures the body temperature
based on the infrared energy emitted from the eardrum or
the forehead. Users can quickly get measurement results
after positioning properly the temperature probe in the ear
canal or forehead.
Normal body temperature is a range. The following tables
shows that this normal range also varies by site. Therefore,
readings from different site should not be directly compared.
Tell your doctor what type of thermometer you used to take
your temperature and on what part of the body. Also bear
this in mind if you are diagnosing yourself.
