ABSTRACT:
The present invention is drawn to a non-contact thermometer that is operable to emit a first light having a first color to create a spot of a first color at a reference target and to detect the temperature of the reference target. The non-contact thermometer is additionally operable to establish a temperature difference threshold. In use, once a temperature difference threshold is selected and once the temperature of the reference target is detected, the non-contact thermometer may detect a temperature of another target. Further, if the detected temperature of the other target is outside of the temperature difference threshold as compared to the temperature of the reference target, the non-contact thermometer is operable to emit a second light having a second color to create a spot of a second color at the other target.
