Tips for measuring temperature
Comparison of different measurement methods
The measured values differ when using different measurement
methods. The World Health Organization (WHO) provides
reference values for normal human body temperature values,
specific temperature differences can be found in the overview
below.
Method of measurement Normal body temperature
Rectal temperature 36,6 °C - 38 °C
Oral temperature 35,5 °C - 37,5 °C
Underarm temperature 34,7 °C - 37,3 °C
Ear temperature 35,8 °C - 38 °C
Changes in human body temperature
Man belongs to animal species with a constant temperature.
Body temperature is basically constant, but not completely
constant.
The temperature of the human body changes during the day, as
follows:
At night (lowest)
Body temperature is lowest at night due to sleep and reduced
physical activity.
Morning (higher)
When we move from a heated bed to a lower temperature room
in the morning, the muscles in the body begin to contract and
generate heat.
At noon (highest)
The human body reaches its highest temperature at noon to
allow the body to adapt naturally.
15:00 - 16:00 afternoon (lower)
For physical exertion and reduced blood sugar.
Evening (lowest)
Due to the sunset and lower room temperature.

Advice
Why is it necessary to clean the device after each
measurement?
The infrared thermometer uses a high-sensitivity technique
to measure the temperature of the target object. Earwax or
impurities affect the accuracy of the measurement and at the
same time increase the likelihood of bacterial infection. We
recommend cleaning the product after each use as shown
above.
