II.INTRODUCTION
The AT2102 Infrared Non-Contact Thermometer has been developed using the latest
infrared technology. This technology allows temporal artery (TA) temperature to be
taken at a distance of about 3cm~5cm away from the forehead. Precise,
instantaneous, and without contact, the AT2102 is, up to now, the most suitable
thermometer for temperature measurement. It has been demonstrated that this
method of TA temperature measurement is more precise than the tympanic
thermometry and better tolerated than rectal thermometry (1).
However, as with other types of thermometers, it is essential to use the AT2102
properly in order to obtain reliable and stable results. You are therefore advised to
read this instruction manual and the safety precautions carefully before use.

III.PRECAUTIONS BEFORE USE
In order to obtain reliable and stable results, you are advised each time there is a
significant change in the ambient temperature due to a change in environment, to
allow the AT2102 to acclimatize to the new ambient temperature for 15 to 20
minutes before using it.
It is important to allow a 1 minute interval between each measurement.
IV. OPERATING PRINCIPLE
All objects, solid, liquid, or gas, emit energy by radiation. The intensity of this energy
depends on the temperature of the object. The AT2102 infrared thermometer is
therefore able to measure the temperature of a person by the energy the person
The AT2102 is pre-set at the factory.
It is not necessary to calibrate the device when starting it up.

emits. This measurement can be taken thanks to an external temperature probe on
the device which analyses and registers the ambient temperature. Therefore, as soon
as the operator holds the thermometer near the body and activates the infrared
sensor, the measurement is taken instantly by detection of the infrared heat
generated by the arterial blood flow. Body heat can therefore be measured without
any interference from the heat of the surrounding environment.
THE DIFFERENT METHODS OF TEMPERATURE MEASUREMENT
Core temperature
Core temperature is the most precise measurement and involves measuring the
temperature in the pulmonary artery by means of a catheter equipped with a
thermal probe which can read the temperature in situ. The same method is
employed for probes measuring the esophageal temperature. However, such invasive
temperature measurement methods require specific equipment and expertise.
Rectal thermometry
Rectal temperature adjusts slowly in comparison to the evolution of the body’s
internal temperature. It has been demonstrated that rectal temperature remains
raised long after the internal temperature of the patient has started to drop and vice
versa. Furthermore, rectal perforations have been known to occur as a result of this
method and without appropriate sterilization techniques, rectal thermometry can
spread germs often found in feces.
Oral thermometry
Oral temperature is easily influenced by recent ingestion of food or drinks and by
breathing through the mouth. To measure oral temperature, the mouth must remain
closed and the tongue lowered for three to four minutes which is a difficult task for
young children to accomplish.
Axillary (armpit) temperature
Although it may be easy to measure axillary temperature, it has been proven that it
does not provide an accurate measurement of the child’s internal temperature. To
take this type of temperature, the thermometer must be wedged tightly over the
axillary artery. Despite the low sensitivity and relative inaccuracy of axillary
temperature in detecting fever, this method is recommended by The American
Academy of Pediatrics as a screening test for fever in newborns.
Tympanic Thermometry
In order to obtain a precise temperature reading, good command of the

4
measurement technique is required. The thermometer probe must be placed as
close as possible to the warmest part of the external ear canal. An incorrectly placed
probe could lead to a false temperature reading.

The temperature of the human body varies throughout the day. It can also be
influenced by numerous external factors: age, sex, type, thickness of skin, etc.
ADVANTAGES OF TEMPORAL ARTERY (TA) TEMPERATURE
Infrared arterial temperature can be measured using a device placed on the forehead,
in the temporal artery region. It has been demonstrated that this relatively new
method of measuring temperature is more precise than tympanic thermometry and
better tolerated than rectal thermometry.
The AT2102 thermometer has been designed to produce an instant forehead
temperature reading without any contact with the temporal artery. As this artery is
quite close to the surface of this skin and therefore accessible and given the blood
flow is permanent and regular, it allows precise measurement of the temperature.
This artery is linked to the heart by the carotid artery which is directly linked to the
aorta. It forms part of the main trunk of the arterial system. The efficiency, speed,
and comfort of taking a temperature from this area makes it ideal compared with
other temperature measurement methods.

PRACTICAL CONSIDERATIONS WHEN TAKING A TEMPERATURE
- In order to ensure that precise and accurate temperature measurements are
obtained, it is essential that each user receive adequate information on and
training in the temperature measurement technique when using this device.
- It is essential to remember that although procedures such as taking a temperature

5
may be simple they must not be trivialized.
- Temperature should be taken in a neutral context. The patient must not have
undertaken vigorous physical activity prior to taking his/her temperature and the
room temperature must be moderate.
- Be aware of physiological variations in temperature which must be taken into
consideration when evaluating the results: temperature increases by 0.5°C
between 6 am and 3 pm. Women have a temperature that is higher, on average, by
around 0.2°C. Their temperature also varies in accordance with their ovarian cycle.
It rises by 0.5°C in the second half of the cycle and at the early stages of pregnancy.
- When sitting, temperature is lower by about 0.3°C to 0.4°C than when standing.
HOW TO TAKE A TEMPERATURE
Aim at the FOREHEAD over the right temporal
region from a distance of about 3cm~5cm,
press the thermometer’s measurement button,
and the temperature is instantly displayed.
The reliability of the measurement cannot be
guaranteed if the temperature is measured over
another part of the body (e.g. arm, torso, etc.)
CONSTRAINTS
Please observe the following before any temperature measurements to ensure a
stable and reliable result:
- Push back hair from the forehead
- Wipe away any perspiration from the forehead
- Avoid any drafts (e.g. from nasal cannulas, air conditioning, etc.)
- Allow a 1 minute interval between each measurement.
- Each time there is a significant change in the ambient temperature due to a change
in the environment, allow the AT2102 to acclimatize to this ambient temperature
for at least 15 minutes before using it.
