The Braun ThermoScan thermometer has been carefully developed for ac-curate,
safe and fast human body temperature measurements in the ear. The shape of
the thermometer probe prevents it from being inserted too far into the ear canal
which could perforate the tympanic membrane.
However, as with any thermometer, proper technique is critical to ob-
taining accurate temperatures. Therefore, please read all instructions
carefully and thoroughly before using this product.

Important

• Do not expose the thermometer to temperature extremes (below –4 ºF /
• The probe window must be kept clean, dry, and undamaged at all times to
• This thermometer must only be used with genuine Braun ThermoScan probe
• To avoid inaccurate measurements, always attach a new, clean probe cover for
• If the thermometer is accidentally used without a probe cover attached, clean
Braun ThermoScan measures the infrared heat generated by the eardrum and
surrounding tissues. To help ensure accurate temperature measurements, the sen-
sor itself 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 in-frared
energy until a temperature equilibrium has been reached and an ac-curate mea-
surement can be taken.
Why measure in the ear?
Clinical studies have shown that the ear is an excellent site for temperature mea-
surement because temperatures taken in the ear reflect the body's core tempera-
ture
blood supply as the tympanic membrane
usually seen sooner at the tympanic membrane than at other sites, such as the
rectum, mouth or under the arm.
Advantages of taking temperatures at the ear versus traditional sites:
• Axillary temperature measurements reflect skin temperature which may not
• Rectal temperatures often lag significantly behind internal body temperature
• Oral temperatures are often influenced by eating, drinking, thermometer
