Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, specifically a radiation thermometer calibration device. Background Technology

[0002] Radiation thermometers, as non-contact temperature measuring instruments, are widely used in various fields such as industry, medicine, and scientific research due to their unique advantage of not requiring direct contact with the object being measured. Especially in complex environments such as high temperatures, corrosive conditions, or difficult-to-access environments, radiation thermometers demonstrate their irreplaceable practical value. However, like any measuring instrument, radiation thermometers inevitably develop measurement errors during long-term use. Therefore, regular calibration of radiation thermometers is crucial to ensure the accuracy and reliability of their measurement results.

[0003] In traditional methods of calibrating radiation thermometers, blackbody furnaces or standard temperature sources are commonly used calibration devices. However, these traditional methods have a series of problems and limitations.

[0004] First, the complexity of operation is a major drawback of traditional calibration methods. These methods often require sophisticated equipment and cumbersome procedures, demanding a high level of technical skill from the operators. This not only increases the difficulty of calibration but may also introduce human error during the operation, affecting the accuracy of the calibration results.

[0005] Secondly, high cost is a major drawback of traditional calibration methods. Standard temperature source equipment such as blackbody furnaces are expensive, and their maintenance costs are also relatively high. This undoubtedly represents a significant expense for users who need to perform frequent calibrations, increasing their overall operating costs.

[0006] Furthermore, traditional calibration equipment is bulky and inconvenient to carry and move, which greatly limits its application scenarios. Especially in situations requiring on-site calibration, traditional equipment often fails to meet the needs, causing inconvenience to the calibration work.

[0007] Finally, traditional calibration methods also have limitations in temperature control and monitoring. Due to equipment and technological limitations, traditional methods may not be able to accurately control and monitor temperature changes during the calibration process, resulting in low calibration accuracy. This not only affects the calibration effect of the radiation thermometer but may also mislead subsequent measurement work. Utility Model Content
