Digital Infrared Ear Thermometer With LCD Digital Display CE FDA Approval
Human body infrared thermometer
Infrared thermometer consists of optical system, photodetector, signal amplifier, signal processing, display output and other parts. The optical system gathers the target infrared radiation energy in its field of view, and the size of the field of view is determined by the optical parts of the thermometer and its position. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal. The signal passes through the amplifier and the signal processing circuit, and is converted into the temperature value of the measured target after being corrected according to the internal therapy algorithm and target emissivity of the instrument.
