Key factors on the accuracy of measurement temperature by using infrared thermometer

摘要

The key factors on measurement accuracy of infrared thermometer are investigated by experimental analysis. In this study, the temperature of a certain DC/DC power module is measured under various kinds of condition by using infrared thermometer(FEI, MWIR-512). It is found that the electric parameters, magnification of objective lens and measurement environment condition have significant effect on the temperature measurement accuracy.
