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.
