The Braun ThermoScan thermometer has been carefully developed for accurate, safe and fast temperature measurements in the ear.
The shape of the thermometer probe prevents it from being inserted too far into the ear canal, which can hurt the eardrum.
However, as with any thermometer, proper technique is critical to obtaining accurate temperatures. Therefore, read the instructions carefully and thoroughly.
The Braun ThermoScan thermometer is indicated for intermittent measurement and monitoring of human body temperature for people of all ages. It is intended for household use only.
Use of IRT6515 along with Fever guidance feature is not intended as a substitute for consultation with your physician.
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.
Temperature guidance helps you to better understand the meaning of your child's temperature with the color indicated on the display. The screen displays a green, yellow, or red backlight depending on the temperature reading.
It is important to note that a patient's temperature may be impacted by age, gender or medical condition, or by factors such as ambient temperature, time of day, medications taken or the temperature measurement site1.
Color range | Reading | Meaning |
Green | >96.3°F - 99.4°F (>35.7°C - 37.4°C) | Normal |
Yellow | >99.4°F - 101.3°F (>37.4°C - 38.5°C) | Fever |
Red | >101.3°F (>38.5°C ) | High Fever |
Note: Backlight remains OFF when below temperature readings are registered: 93.2≤T≤ 108°F (34 ≤ T ≤ 42.2°C)
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.
The goal of thermometry is to measure core body temperature[2], which is the temperature of the vital organs. Ear temperatures accurately reflect core body temperature,[3] since the eardrum shares blood supply with the temperature control center in the brain,[4] the hypothalamus. Therefore, changes in body temperature are 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.
ALWAYS replace disposable lens filters to maintain accuracy and hygiene. A measurment taken in the right ear may differ from a measurement taken in the left ear. Therefore, ALWAYS take the temperature in the same ear. The ear must be free from obstructions or excess earwax build-up to take an accurate reading.
External factors may influence ear temperatures, including when an individual has:
Factor | Affects |

Used lens filter | ![]() |
Dirty lens | ![]() |
In the cases below, wait 20 minutes prior to taking a temperature. | |

Use the untreated ear if ear drops or other ear medications have been placed in the ear canal. Use the ear that has been facing upwards, if an individual has been lying down on their side with an ear facedown on a pillow.
The thermometer includes a convenient night light to illuminate the display in a dim environment.
The light will turn on when you press any button. It will stay on until the thermometer is inactive for up to 15 seconds even after temperature is taken.
Your Braun ThermoScan is shipped with the Fahrenheit (°F) temperature scale activated. If you wish to switch to Celsius (°C) and/or back from Celsius to Fahrenheit, proceed as follows:
The probe tip is the most delicate part of the thermometer.
It must be clean and intact to ensure accurate readings.
If the thermometer is ever accidentally used without a lens filter, clean the probe tip as follows:
Very gently wipe the surface with a cotton swab or soft cloth moistened with alcohol. After the alcohol has completely dried out, you can put a new lens filter on and take a temperature measurement.
If the probe tip is damaged, please contact Consumer Relations.
Use a soft, dry cloth to clean the thermometer display and exterior. DO NOT use abrasive cleaners. NEVER submerge this thermometer in water or any other liquid. Store thermometer and lens filters in a dry location free from dust and contamination and away from direct sunlight.
Additional lens filters (LF 40) are available at most stores carrying Braun ThermoScan.
The thermometer is initially calibrated at the time of manufacture. If this thermometer is used according to the use instructions, periodic re-adjustment is not required. If at any time you question the accuracy, please contact Consumer Relations.
Error message | Situation | Solution |
![]() | No lens filter is attached. | Attach new, clean lens filter. |
![]() | The thermometer probe was not positioned securely in the ear. An accurate measurement was not possible. POS = position error | Check if the positioning of the probe is correct and remains stable. Replace lens filter and reposition. Press Start button to begin a new measurement. |
![]() | Ambient temperature is not within the allowed operating range (50 – 104°F or 10 – 40°C). | Allow the thermometer to remain for 30 minutes in a room where the temperature is between 50 and 104°F or 10 and 40°C. |
![]() | Temperature taken is not within typical human temperature range (93.2 – 108°F or 34 – 42.2°C). HI = too high LO = too low | Make sure the probe tip and lens are clean and a new, clean lens filter is attached. Make sure the thermometer is properly inserted. Then, take a new temperature. |

This thermometer is intended for household use only. Use of this thermometer is not intended as a substitute for consultation with your physician.
This thermometer is not intended for pre-term babies or small-for-gestational-age babies. This thermometer is not intended for pre-term babies or small-for-gestational age newborn (birth to 4 weeks of age) babies. Pre-term is defined as babies born before 37 weeks of gestation. Small-forgestational-age is defined as a newborn baby, born at 37 weeks or later, with a weight below the 10th percentile for newborn babies of the same gestational age.
Nursing mothers should not take a temperature measurement on themselves or have their temperature measured by another individual while or immediatley after nursing a baby, as nursing can affect body temperature.
It is not intended to interpret hypothermic temperatures. If the device displays a temperature of 97.5°F (36.4°C) or less with an LED backlight color of green or white, and the individual is exhibiting atypical symptoms or behaviors, contact your doctor or health care professional.
DO NOT allow children under 12 years to take their temperature unattended.
DO NOT modify this equipment without authorization of the manufacturer.
People who are on antibiotics, analgesics, or antipyretics should not be assessed solely on temperature readings to determine the severity of their illness.
Temperature elevation may signal a serious illness, especially in neonates and infants, or in adults who are elderly, frail, or have a weakened immune system. Please seek professional advice immediately when there is a temperature elevation and if you are taking temperature on:
