The Braun ThermoScan Thermometer has been
carefully developed for accurate, safe and fast
temperature measurements in the ear.
The shape of the thermometer prevents it from being
inserted too far into the ear canal to damage the
eardrum.
However, as with any thermometer, proper
technique is critical to obtaining accurate
temperatures. Therefore, read the use
instructions carefully and thoroughly.
Important
• The operating ambient temperature range for this
thermometer is 10 – 40 °C (50 – 104 °F).
• Do not expose the thermometer to temperature
extremes (below –20 °C / 4 °F or over 50 °C /
122 °F) nor excessive humidity (> 95 % RH).
• This thermometer must only be used with genuine
Braun ThermoScan Lens Filters (LF 40). Never use
this thermometer without a new, clean lens filter
attached.
• Keep lens filters out of reach of children.
• This thermometer is intended for household use
only.
• Use of this thermometer is not intended as a
substitute for consultation with your physician.
How does Braun ThermoScan work?
Braun ThermoScan measures the infrared heat
generated by the eardrum and sorrounding tissue.
To help ensure accuracy, the thermometer «scans»
by taking 8 measurements in just one second and
displaying the highest temperature.
Why measure in the ear?
The goal of thermometry is to measure core body
temperature which is the temperature of the vital
organs. Ear temperatures accurately reflect core
body temperature, since the eardrum shares blood
supply with the temperature control center in the
brain, the hypothalamus. Therefore, changes in body
temperature are reflected sooner and more accura-
tely in the ear than at other sites.
• Axillary temperatures only measure skin
temperature and therefore, are not a reliable
indicator of core body temperature.
