Meanwhile, the error is larger because the temperature measuring distances are different in various occasions.
One important reason for the error is that when the infrared thermometer is used, the size of the infrared field of view changes with the change of the measurement distance, and the change rule is different according to the difference of the focusing of the optical lens, which can be generally understood as that the infrared thermometer is the smallest at the focal point and gradually increases after being out of focus, because the infrared thermometer measures the average temperature in the field of view, and the data obtained by taking the average temperature when the field of view is large are more, and the temperature of an irrelevant object around the target object may be taken in, thereby causing the error.
The invention aims to solve the technical problems and provides an infrared temperature detector which adopts a distance measuring sensor arranged at the front end of a temperature detector main body side by side with the temperature measuring sensor to measure the temperature at each time, provides field-of-view information according to parameters such as field angle and the like and gives a prompt.
