Using an Infrared Thermometer's Extra Functions

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.


Other common features include...

  • an Avg. of temperatures recorded during a given measurement
  • a Dif. feature that displays the difference between the highest and the lowest temperatures recorded and...
  • adjustable Hi/Lo Alarms that will flash or beep when a recorded measurement goes above or below a designated temperature


These extra features are particularly useful in food service or industrial settings where fixed operating procedures or government regulations specify adherence to certain temperature ranges.
