1. Is it harmful to human body if the bi-spectrum thermal camera is used to measure the temperature of human body?

The infrared thermal camera in the dual-light equipment for human body temperature measurement passively receives the infrared radiation emitted by the human body to image and measure the temperature, so the human body temperature measurement by the dual-light equipment of human body temperature measurement has no harm to the human body.

2. Why is the temperature measured by the dual-light equipment generally lower than the temperature of the human body?

The dual-light human body temperature measurement equipment is the measurement of the human body surface temperature, the normal human face temperature is about 2℃ lower than the temperature under the armpit, and the face is affected by the environment changes greatly, so the medical clinical reference of the body temperature under the armpit as the medical temperature measurement. The difference value of the medical temperature measuring gun has been revised and the relevant range has been limited by the software before leaving the factory. The dual-light equipment for human body temperature measuring gives a more real feedback to the temperature measurement.

3. Does it affect the temperature measurement when you just enter the room from the outdoor low-temperature environment? How to solve it?

First, select the appropriate testing site to avoid the impact of ambient temperature on human body temperature, in order to improve the accuracy of temperature measurement. For example, in winter, the outdoor temperature is low and will reduce the temperature of the body surface, so it is recommended to choose indoor constant temperature place for temperature measurement.

Secondly, as the personnel enter the indoor environment from the outside, the measurement value will be low, and the test personnel can expose the wrist and the lower part of the neck covered by the clothing to obtain the relatively accurate measurement value. If high precision measurement is needed, please stay in the room for 5 minutes, and measure again after the body surface temperature returns to normal.

4. Will the installation distance affect the temperature measurement results?

There is a great relationship between the body temperature and the target distance. Close range test will lead to high measurement value, and distance test will lead to low measurement value. Yoseen Infrared human body temperature measuring therma camera is calibrated according to 5-6 meters. It is recommended to install and use the divice according to this distance.

5. What is blackbody? Does the purchaser have to match the blackbody with the body temperature measurement equipment?

The blackbody is an ideal radiator for temperature correction.

The dual-light equipment for measuring temperature of human body must be used with blackbody to avoid the influence of ambient temperature on measuring temperature of equipment and improve the measuring precision of equipment.
