How to Use a Thermoscan Ear Thermometer

Braun ThermoScan is a digital thermometer that measures infrared heat in the ear to determine the core body temperature within seconds. According to Braun, a normal ear temperature ranges from 95.9 to 99.5 degrees F. However, this range can vary depending on the person's age and time of day. In order to determine the normal temperature range, use the ThermoScan to take the person's temperature several times throughout the day while he or she is healthy.
