AI Technical Summary
Existing technologies make it difficult to accurately evaluate the temperature measurement error of infrared thermometers in radiant heating environments, and contact temperature measurement methods are limited and inaccurate.
An equivalent blackbody device is used to introduce an equivalent blackbody into the radiative heating environment. The temperature of the equivalent blackbody is measured by a standard infrared thermometer and thermocouples. The temperature measurement error is calculated by combining the data acquisition device, thus avoiding the interference of heater radiation light and the influence of target emissivity changes.
This invention enables accurate temperature measurement of infrared thermometers in radiant heating environments, solving the problem of not being able to obtain the true temperature of specimens in radiant heating environments and improving the accuracy and reliability of temperature measurement.
