Any object can generate certain proportion of infrared radiant energy
as per its own temperature. The radiant energy and its wavelength
distribution are subjected to its surface temperature. Based on this
principle, this thermometer is designed to detect infrared radiation
at 5~14um by highly precise infrared sensor. By adopting this high
quality sensor plus special calculation and calibration, this thermometer
is able to take accurate body temperature.
2.Working principle
3.Safety precautions
This is a Non-Contact Forehead Thermometer applicable to forehead
measurement. The thermometer measures body temperature by
collecting heat radiation emitting from forehead. New probe
structure is adopted in this thermometer. It's simply operational,
hygeian, reliable and highly accurate. Users can get precise reading
within one second byone touch. This thermometer is cost-effective
and is widely used in schools, customs, hospitals and for family use.
Intended Use & Indication for use: The Non-Contact Forehead
Thermometer is an infrared thermometer intended for the intermittent
measurement of human body temperature in people of all ages.
This thermometer is classified as a Class IIa(for CE)/class II(for FDA)
MedicalDevice, sorted as internally- powered equipment and type
BF application device. It's prohibited to use this thermometer in
flammable anesthetic gas or gas mixture of air and oxygen or
nitrous oxide. This is a continuous operation equipment.

The device is precision instrument, don’t drop, tramp or
impose any vibration or impact on the thermometer.
Do not touch the lens of the probe with your fingers and
disassemble the device by yourself.
Please make sure your forehead is clean before measuring
forehead temperature.
Please stay still indoors about 30 minutes after exercise, eating
or bathing before measuring.

ambient temperature varies a lot before using.
Please collect the record of Individual temperature under the
good condition of body in usual days as a reference for checking
fever or not.
Do not measure the sites of scarred tissue or tissue
compromised by skin disorders because they will affect the
accuracy of measurement.
Do not measure if patient is treated with certain drug therapies
because body temperature may rise in the drug within the effort
time limit.
Do not immerse the device into water or any other liquid, do not
expose to the sun.
Do not use a mobile or cordless phone near the thermometer
measuring. Do not use the thermometer near a mobile or
cordless phone.

The Infrared thermometer is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
Infrared thermometer can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Infrared thermometer as recommended below, according to

b. Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM

To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in
the location in which the Infrared thermometer is used exceeds the applicable RF
compliance level above, the Infrared thermometer should be observed to verify
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the Infrared thermometer.
