Section 1: Overview
Description of Non Contact Infrared Body Thermometer
• Device principle and introduction:
The Non Contact Infrared Body Thermometer is a hand-held, reusable, battery operated
device, which can measure human body temperature using the forehead as the
measurement site (the skin temperature on one’s forehead.) The operating principle is based
on Infrared (IR) Sensor technology. When measuring, the IR Sensor acquires infrared energy
from the target forehead. Taking into account the ambient temperature, the thermometer
turns the signal from the IR Sensor to a digital value and displays it on the LCD.

• Before using, allow the thermometer to remain in the room in which it will be used for
30 minutes. The room temperature should be between 59°F and 95°F (15°C and 35°C).
• The ambient temperature around the test person should be stable. DO NOT take human
temperature measurements near air flow from fans, air-conditioning vents, etc.
• When people move from a place of lower temperature a place of higher temperature,
they should remain in the test environment for at least 5 minutes, to be consistent with
the ambient temperature before their temperature is measured.
• In the event that you can’t follow the ambient acclimation guidance due to using this
device as a screening tool, the reading displayed may shift up or down as a result of the
temperature subjects are coming from compared to the temperature they are being
measured in. If that is the case, judge individuals against each other, and any individual
that is reading 1.5°F (0.8°C) higher or lower than the normal, should be measured again
following acclimation.
• Wait at least 1 second for the next measurement. If measuring continuously five times,
it is recommended to wait at least 30 seconds and then continue measurement.
• DO NOT use this thermometer in direct sunlight.
3: General Setup and Use
• Start measuring

“double beeps” for an elevated temperature, which means that the measurements have
been completed. The target value of the measured temperature is displayed on the LCD,
while the backlit displays one of three colors red, green, yellow. Green means ready for
the next measurement. If 99.3°F – 101.1°F (37.4°C-38.4°C), yellow is displayed, which
means slight fever warning. Please pay attention to body temperature. When the body
temperature is above 101.1°F, red is displayed, which means high fever. Please take action
