Non-contact Infrared Thermometer
Instruction Manual
- Product overview
NX-2000 non-contact infrared thermometer (hereinafter referred to
as thermometer) is a thermometer that uses infrared technology to
detect thermal radiation for measuring human body temperature. When
in use, you can simply point the head of infrared thermometer to
the forehead to quickly and accurately measure the human body
temperature. The infrared thermometer is a professional instrument
for quickly monitoring body temperature in traffic-intensive public
sites. With advantages of non-contact, high accuracy, fast
measurement, over-temperature voice alarm, it is particularly
suitable for use at exit-entry ports, ports, airports, wharfs,
stations, institutions, schools, theaters, etc. See figure 1.

- Basic principle
Every object of a temperature higher than absolute zero will emit a
portion of infrared radiation according to its own temperature. The
amount and wavelength distribution of infrared energy emitted by an
object are significantly correlated with its surface temperature.
The infrared wavelength of human body temperature (36-37℃) is 9~13
q m, according to this principle, the infrared thermometer can
accurately detect the surface temperature on the forehead to
display accurate readings by inferring the actual body temperature.
3. Product features
1) Special design for measuring forehead temperature, dynamic
compensation of ambient temperature and forehead temperature;
2) Exclusive use of high-precision infrared temperature probe, more
stable measurement accuracy and performance;
3) Backlit LED digital display;
4) Fahrenheit and Celsius dual-mode options;
5) Select forehead thermometer mode to measure object temperature
with an emissivity of 0.95 in the range of 100°.

5. Operation instructions
.Measurement mode setup:
After power on, the screen displays the current measurement mode.
Press the "mode setting" button to switch the measurement mode to
body temperature and surface temperature.
Press and hold the "set" key, when the "
" is displayed on the screen, the sound prompt will be turned on.
Press the "set" key again, the "" on the screen disappears, and the sound prompt will be turned
off;
Long press the "set" key to switch between "Fahrenheit" (° F) or
"Celsius" (° C) temperature units.
Note:
The body temperature mode is used to measure human body
temperature, which is inferred from dynamic compensation of
difference between ambient temperature and forehead surface.
- Use method
Confirm the measurement mode on the screen is body temperature
mode. Point the head of infrared thermometer vertically to the
center of the forehead, at a distance approximately 3-5cm. Press
“MEASURE” button, 1 second later you will hear a “beep” and see the
readings on the screen.
If the temperature exceeds the alarm value, the infrared
thermometer will prompt you with warning tone of 5 beeps.
