An infrared temperature sensing device, this infrared thermometer works with a temperature calibration program. It displays accurate results and its ergonomic body shape enhances the wearable experience, making it easy to operate. Any object emits infrared radiation energy, and the temperature of its surface directly determines the size and wavelength of the radiation energy. This thermometer uses a high-precision infrared sensor to detect infrared radiation coming from the human body, with a wavelength of 5-14 microns. Accurately measure the temperature of the human body through complex calculations and compensation corrections. Features LCD display measures in Fahrenheit or Celsius stores 32 sets of measurements body and surface modes Model: HZK-801
