Methods of measuring temperature
It is important to remember that the body temperature reading depends on the site where it is
measured. For this reason, the measurement site must always be specified in order to ensure that
a correct temperature reading is recorded.
In the rectum (rectal)
This is the most accurate method from a medical point of view, because it comes closest to the
core body temperature. The thermometer tip is inserted carefully into the rectum for a maximum
of 2 cm.
The usual measuring time is approximately 40 to 60 seconds.
Under the arm (axillary)
Placing the thermometer in the armpit provides a measurement of surface temperature that can
fluctuate by around 0.5°C to 1.5°C from rectal temperature readings in adults. The usual
measuring time for this method is approximately 80 to 120 seconds. It should be noted, however,
that an exact reading cannot be obtained if, for example, the armpits have been allowed to cool.
If this is the case, we recommend extending the measuring time by around 5 minutes in order to
obtain the most precise possible reading that corresponds as closely as possible to the core body
temperature.
In the mouth (oral)
There are different heat zones in the mouth. As a general rule, the oral temperature is 0.3°C to
0.8°C lower than the rectal temperature. To ensure that reading is as accurate as possible, place
the thermometer tip to the left or right of the root of the tongue. The thermometer tip must have
constant contact with the tissue during the reading and be placed under the tongue in one of the
two heat pockets at the back, keep the mouth closed during the reading and breathe evenly
through the nose. Do not eat or drink anything before the measurement. The usual measuring
time is approximately 50 to 70 seconds.
Note: We strongly recommend the rectal method as the most accurate method for identifying the
temperature, and advise you to extend the measuring time by 3 minutes after the beep.
Cleaning and disinfection
The best way to clean the thermometer tip is by applying a disinfectant (e.g. 70% medical
alcohol) with a damp cloth.
It shall be disinfected before each use. This thermometer is warned not waterproof and can not
be immersed in liquid or any other kind of water for through cleaning and disinfection.
Safety precautions
•
Do not allow the device to come into contact with hot water.
•
Do not expose to high temperatures or direct sunlight.
•
Do not drop the thermometer. It is neither shock-proof or impact-resistant.
•
Do not modify this device without the authorization of the manufacturer.
•
Do not bend or open the device (except the battery compartment).
•
Do not clean with thinners, petrol or benzene. Only clean with disinfectant.
•
Do not immerse the thermometer in liquid.
