1. Introduction
IT-121 measures the body temperature through receiving the infrared energy
radiation from the surface of objects. It is with forehead temperature mode,and ear
temperature mode. The measurement result directly shows on the LCD screen It is
easy, hygiene and accurate.
The device is widely used for home healthcare, medical institutes and many other
occasions.
The product is mainly composed with infrared temperature sensors, signal
receiving processor, buttons, buzzer, LCD display, battery, etc
1.1 Product intended use
The infrared thermometer is intend for the measurement and monitoring of
human body temperature by doctor or customers in the hospital or home, it is used
alone for human beings for all ages.
2. principle
Any object in which temperature is higher than absolute zero degree will transmit
some infrared radiation energy according to its own temperature. The radiation
energy and its distribution per wavelength are closely associated with its surface
temperature. Based on the principle, it is possible to measure the forehead surface
temperature and then adjust the offset between forehead temperature and actual body
temperature, which will result in the correct display of body temperature.
3. Product features
