China Home High-Precision Contactless Human Body Spot Infrared Forehead Temperature Gun

1: Product Description
The infrared forehead thermometer produced by our company is a kind of measuring instrument for measuring human body temperature based on the principle of infrared receiving. When in use, as long as the detection window is conveniently aligned with the forehead position, the human body temperature can be measured quickly and accurately. The instrument has functions such as detection, storage and query.
Can be used for newborns, children and adults. Infants and children cannot operate the thermometer and it is recommended that the temperature be measured by an adult.
2: Detection principle
HB-FT900A infrared forehead thermometer detection principle:All objects whose temperature is higher than absolute zero will emit a proportion of infrared radiation energy according to their own temperature. The amount of radiant energy and its distribution by wavelength are very closely related to its surface temperature. The infrared wavelength radiated by the human body at the temperature (36 ~ 37 ° C) is 9 ~ 13μm. According to this principle, the surface temperature of the forehead can be accurately measured, and the correct body temperature can be displayed by correcting the temperature difference between the forehead and the actual body temperature.

5: Instructions
The correct operation method is the key to measurement accuracy. Because infrared temperature measurement has high requirements on the ambient temperature, please pay attention to the following tips when using it.
1)When measuring body temperature, please point the meter at the forehead. The measurement site must not be covered by hair, sweat, hats, etc. At the same time, please keep the measurement distance (1 ~ 3) cm.
2)If the person to be measured comes from a place with a large difference in ambient temperature (such as low outdoor temperature and high indoor temperature), they should wait for 30 minutes, and then be measured when their body temperature is consistent with the measured ambient temperature.
3) Fever patients with cold foreheads, sweating, and other cooling measures will cause low measurement results, and measurement in this case should be avoided.
4)Cannot be measured in places with large air flow such as air conditioner outlets or under fans.
6: Memory function
The measured temperature value will be stored automatically. In the power-on state, shortly press the (MEMO) button to count into the memory function. Shortly press the(MEMO)button again to view the more recently stored data.
