The non-contact handheld human body temperature detector detects the human body temperature of influenza and various other influenza (epidemic) and virus fever temperatures. If a suspicious fever patient is encountered, the instrument will immediately prompt and effectively prevent cross infection of abortion. The fever alarm has high sensitivity for measuring body temperature, wide detection range, fast speed, does not interfere with the measured target, non-contact measurement of human body temperature, and is safe to use.

Application: AWH238 handheld human body temperature detector has non-contact measurement of human body temperature with high accuracy. Especially suitable for use in crowded places such as entry and exit ports, harbors, airports, docks, stations, hospitals, schools, kindergartens, sports venues, hotels, entertainment venues, and factories.

Function: Designed specifically for measuring human forehead temperature, dynamically compensating for ambient temperature and forehead temperature. High measurement accuracy and more stable performance; It has a prompt function when the human body temperature is too high and can store measurement data; Backlit liquid crystal (LCD) display; There are two modes to choose from, Fahrenheit and Celsius, with automatic shutdown and power-saving function. This product does not emit red laser radiation when detecting human body temperature, and is a sensor based temperature detection suitable for medical non-contact detection of human body temperature.

Principle:

In nature, all objects with temperatures above absolute zero are constantly emitting infrared radiation energy into the surrounding space. The magnitude and wavelength distribution of infrared radiation energy of an object are closely related to its surface temperature. Therefore, by measuring the infrared energy radiated by an object itself, its surface temperature can be accurately determined, which is the objective basis for infrared radiation temperature measurement.

The optical system concentrates the infrared radiation energy of the target within its field of view, and the size of the field of view is determined by the optical components and their positions of the thermometer. Infrared energy is focused on the photodetector and converted into corresponding electrical signals. The signal is amplified and processed by a signal processing circuit, and then converted into the temperature value of the measured target after being calibrated according to the algorithm and target emissivity built-in in the instrument.
