This IR gun has a 1:10 measurement cone, meaning that the area sensed is one foot in diameter when it is ten feet from the gun. Operation is straightforward: pull the trigger, position the laser pointer on the area to be measured, and read the display which backlights for operation in darkness. Both the instantaneous temperature and the maximum temp during this trigger pull are displayed. No data is stored; each trigger pull takes a new reading.
Fluke is one of the premier manufacturers of electrical test equipment. This is their basic model. It is solidly made, with a rubberized housing that would make it resistant to damage from reasonable drops. We give it a Bronze medal for meeting expectations and ease of use. It appears that this model may be out of production, but the link to Amazon below redirects you to a replacement model which we have not tested.
