Body temperature
Normal body temperature is a range. It varies by site of measurement, and it tends to decrease
with age. It also varies from person to person and fluctuates throughout the day. Therefore, it is
important to determine normal temperature ranges. This is easily done using Braun ThermoScan.
Practice taking temperatures on yourself and healthy family members to determine the normal
temperature range.
Note: When consulting your physician, communicate that the ThermoScan temperature is a
temperature measured in the ear and if possible, note the individual's normal ThermoScan
temperature range as additional reference.
Age Precision™ color-coded display
Clinical research shows the definition of fever changes as newborns grow into children and children grow
into adults.

Select the appropriate age setting, take a temperature, and the display will glow green, yellow, or red to
indicate whether the temperature is in a normal, fever, or high fever range, respectively. The device is only
intended for the measurement of human body temperature. It is not intended to diagnose or monitor a
serious medical condition or disease.

How does Braun ThermoScan work?
Braun ThermoScan measures the infrared heat generated by the
eardrum and surrounding tissues. To help avoid inaccurate temperature
measurements, the probe tip is warmed to a temperature close to that of the human
body. When the Braun ThermoScan is placed in the ear, it continuously monitors the
infrared energy. The measurement is finished and the result displayed when the
thermometer detects that an accurate temperature measurement has been taken.
Why measure in the ear?
The goal of thermometry is to measure core body temperature
temperature of the vital organs. Ear temperatures accurately reflect core body
temperature,
since the eardrum shares blood supply with the temperature control
2
center in the brain,
the hypothalamus. Therefore, changes in body temperature are
3
reflected sooner in the ear than at other sites. Axillary temperatures measure skin
temperature and may not be a reliable indicator of core body temperature. Oral
temperatures are influenced by drinking, eating and mouth breathing. Rectal
temperatures often lag behind changes in core body temperature and there is
a risk of cross-contamination.
