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 uctuates 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.
Why measure in the ear?
The goal of thermometry is to measure core body temperature
1
, which is the temperature
of the vital organs. Ear temperatures accurately reect core body temperature,
2
since the
eardrum shares blood supply with the temperature control center in the brain,
3
the
hypothalamus. Therefore, changes in body temperature are reected 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 inuenced by drinking, eating
and mouth breathing. Rectal temperatures often lag behind changes in core body
temperature and there is a risk of cross-contamination.
Age Precision

Technology
Clinical research shows the denition 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. When placed in the ear, Braun ThermoScan continuously monitors the infrared energy
and the ExactTemp® Stability Indicator displays a reading only if the thermometer detects that
an accurate and stable temperature measurement has been taken.
