Operational principle	The optical system gathers
the infrared radiation energy
of the target in its field of
view, size of which depends
on the optical parts and their
positions. The gathered
infrared energy is focused on
the photoelectricity detector
and converted to be the
electrical signal accordingly.
After passing through the
amplifier and signal
processing circuit, the
electrical signal will be
converted to be the
temperature of the measured
target according to the
algorithm internally
contained in the device and
target emissivity correction.	The thermometer uses a
thermopile sensor with
integrated thermistor for the
target reading, a thermistor
mounted in the head of the
thermometer for ambient
temperature readings, a
parabolic mirror to help focus
the infrared energy emitted
from the forehead, and an
infrared proximity sensor for
detection of contact or non-

Comparison of technological characteristics with the predicate device

Discussion for similarities and differences:

1. Intended use(s)/Indication for use: indication for use of the subject device has the similar meaning with different words as the predicate device. In addition, the subject device has more restricted people age range than the predicate device. Such difference will not affect the safety and effectiveness of the subject devices.
1. Temperature measurement range: the subject devices measurement range from 32 ℃~~43 ℃ (89.6 °F~~109.4 °F), which is different from the predicate device's measurement range, 34.4℃ ( 93.9F ) – 42.2℃ (108°F ). While the subject devices have been tested and validated according to standard ISO 80601-2-56 including clinical accuracy and the measuring range of the subject devices meet the minimum rated output range of clinical thermometer requirement, from 35°C to 42°C, therefore, such difference will not affect the safety and effectiveness of the subject devices.

Electric safety and EMC: the batteries used in the subject device are rechargeable batteries, different 3. from the predicate device, and tested according to IEC 62133-2. Such difference between the predicate device and the subject device will not affect the safety and effectiveness of the subject device.
Power requirements: the subject devices are powered with rechargeable li-ion battery pack and 4. different from the predicate device, which is powered with 2 AA batteries. The rechargeable battery pack has been tested according to IEC 62133-2: 2017, the differences between the predicate device and subject device will not affect the safety and effectiveness of the subject device.
Patient contact materials: there are some material differences between the subject devices and the 5. predicate device, but biocompatibility of both the subject devices and the predicate device has been evaluated and tested according to ISO 10993 series and FDA guidance. The patient contact materials have passed the biocompatibility testing in accordance with ISO 10993-1:2009, ISO 10993-5:2009, ISO 10993-10:2010. Such difference between the predicate device and subject device will not affect the safety and effectiveness of the subject device.
