All but the most basic infrared thermometers will provide recording features like a Max/Min function, that displays the maximum or minimum temperature recorded during a given measurement.
These features work best when you sweep the thermometer's field of view across a given range of targets to see variance. They often reset each time the thermometer's measurement trigger is pressed, giving you a different Min. or Max. each time you scan. Check your particular thermometer's user guide for more details.
