This clinical thermometer is intended for non-contact measurement of forehead, object and room temperature. It allows you to quickly and easily measure body temperature. Values are saved automatically.
The temperature measurement varies depending on the part of the body where the measurement is taken. In a healthy person, the variance can be between 0.2°C and 1°C (0.4°F and 1.8°F) in different parts of the body.
Normal temperature range with various thermometers
Measurements | Thermometer used | |
Forehead temperature | 35.8°C to 37.6°C (96.4°F to 99.7°F) | Forehead thermometer |
Ear temperature | 36.0°C to 37.8°C (96.8°F to 100.0°F) | Ear thermometer |
Oral temperature | 36.0°C to 37.4°C (96.8°F to 99.3°F) | Conventional thermometer |
Rectal temperature | 36.3°C to 37.8°C (97.3°F to 100.0°F) | Conventional thermometer |
Beurer tip
Holding the thermometer for too long in the hand before taking a measurement can cause the device to warm up. This means the measurement could be incorrect.
Influences on body temperature
Beurer tip
Taking the body temperature provides a current measurement of a person's temperature. If you are uncertain about interpreting the results or if the values are abnormal (e.g. fever), please consult your doctor. This also applies in the case of slight temperature changes if there are other symptoms of illness such as agitation, severe sweating, flushed skin, fast pulse rate, tendency to collapse, etc.

After a brief self-test and two short beeps the thermometer is ready for forehead measurement.
Briefly press the On/Off button .
After a brief self-test and two short beeps the thermometer is ready for forehead measurement. The device always starts up in forehead temperature mode .
This menu allows you to set the following functions individually, one after another.
Time format
Date
The year flashes in the display (fig. 2).
Time
The time flashes in the display (fig. 4).
Temperature meas. unit
The temperature measurement unit flashes in the display (fig. 5).
You can set the device to display the temperature in degrees Celsius (°C) or degrees Fahrenheit (°F).
Acoustic signal
The acoustic signal symbol flashes in the display (fig. 6).
You can activate/deactivate the acoustic signals (device activation, measurement in progress, measurement completion).
Illuminated display
The light symbol flashes in the display (fig. 7).
You can activate or deactivate the automatic illuminated display (appears following forehead temperature measurement).
You can also activate the illuminated display manually by briefly pressing the LIGHT/SET button.
The display lights up for 5 seconds.
The automatic and manual illuminated display cannot be used while measurement is in progress.
Briefly press the On/Off button
After a brief self-test and two short beeps the device is ready for forehead temperature measurement. The device is in forehead temperature mode. This is indicated by the symbol.
Beurer tip
Remember that
Hold the thermometer 2 to 3 cm from the measuring point. Press the SCAN button and move the thermometer from side to side over the forehead area (fig. 8).
During measurement you will hear short beeps (only if the acoustic signal is activated), which signal that the thermometer has found a new highest measurement.
End of measurement is signalled by a long beep.
Release the SCAN button.
You can now read the measured value.
In addition to the temperature, the fever or no fever
symbols also appear in the display:
The no fever symbol indicates that the body temperature is within normal range; the fever symbol
indicates a measurement equal to or higher than 38°C (100.4°F), which triggers a temperature alarm.
If the acoustic signal is switched on, three beeps will sound once the measurement is complete if the temperature is equal to or higher than 38°C (100.4°F).
The measuring time is usually 2 seconds but may take up to 30 seconds.
When two short beeps sound and the forehead symbol stops flashing, the device is ready to take another measurement.
The measurement is automatically saved with the date/time and the "fever" / "no fever"
classification.
Displaying saved measurements
The device only stores measurements in forehead temperature mode . The device automatically stores the values from the last 60 measurements.
When 60 storage places are exceeded the oldest value is deleted.
The memory can be called up as follows:
Object temperature mode
If you want to measure an object temperature with this thermometer, switch to object temperature mode.
Measurements taken in object temperature mode are not stored.
Room temperature mode
If you want to use the thermometer to measure the room temperature you need to switch to room temperature mode.
Measurements taken in room temperature mode are not stored.
Error message | Problem | Solution |
