II. INTENDED USE
The device is an infrared thermometer intended to
measure forehead temperature of infants and adults
without contacting human body. It can be used by
consumers in household environment and doctor in
clinic as reference.
The EM-Th1 is pre-set at the factory.
It is not necessary to calibrate the device when starting it up.
III.INTRODUCTION
The EM-Th1 Non-contact Infrared thermometer has
been developed by using the latest infrared technology.
This technology allows temporal artery (TA) tempera-
ture to be taken at a distance of about 1.2in~2in away
from the forehead. Precise, Instantaneous and without
Contact, the EM-Th1 is, up to now, the most suitable
thermometer for no risk on temperature measurement. It
has been demonstrated that this method of TA tempera-
ture measurement is more precise than the tympanic
thermometry and better tolerated than rectal thermome-
try (1).
However, as with other types of thermometer, it is
essential to use the EM-Th1 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.

IV.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 EM-Th1 to acclimatize to this ambient
temperature for 15 to 20 minutes before using it.
It is important to allow 3~5 seconds interval between two
measurements.
V. 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 EM-Th1 infrared thermometer is
therefore able to measure the temperature of a person
by the energy the person emits. This measurement can
be taken thanks to an external temperature probe on the
device which permanently analyses and registers the
ambient temperature. Therefore, as soon as the
operator holds the thermometer near the body and
activates the radiation sensor, the measurement is
taken instantly by detection of the infrared heat generat-
ed 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 oesopha-
geal 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 sterilisation techniques,
rectal thermometry can spread germs often found in
faeces.
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 tempera-
ture, it has been proven that it does not provide an
accurate measurement of the child’s internal tempera-
ture. 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 recom-
mended 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 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 tempera-
ture reading.

NORMAL TEMPERATURES ACCORDING TO MEASURE-
MENT METHOD
The temperature of the human body varies throughout
the day. It can also be influenced by numerous external
factors: age, sex, type and thickness of skin…
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 EM-Th1 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 perma-
nent 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 make it ideal compared with other
temperature measurements methods.

NORMAL TEMPERATURES ACCORDING TO AGE
PRACTICAL CONSIDERATIONS WHEN TAKING A
TEMPERATURE
- In order to ensure that precise and accurate tempera-
ture measurements are obtained, it is essential that
each user has received adequate information on and
training in the temperature measurement technique
when using such a device.
- It is essential to remember that although procedures
such as taking a temperature may be simple they
must not be trivialised.
- 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 evaluat-
ing the results: temperature increases by 0.9°F
between 6 am and 3 pm. Women have a temperature
that is higher, on average, by around 0.3°F. Their
temperature also varies in accordance with their
ovarian cycle. It rises by 0.9°F in the second half of
the cycle and at the early stages of pregnancy.
- When sitting, temperature is lower by about 0.5°F to
0.7°F than when standing.
HOW TO TAKE A TEMPERATURE
Aim at the FOREHEAD, over the right temporal region,
from a distance of about 1.2in~2in, press the thermom-
eter’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…)
CONSTRAINTS
Please observe the following before any temperature
measurement 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 air conditioning…)
- Allow a 3-5 seconds interval between measurements.
- Each time there is a significant change in the ambient
temperature due to a change in environment, to allow
the EM-Th1 to acclimatise to this ambient tempera-
ture for at least 15 minutes before use.
