IR devices, like the Fluke 61and 65, make it safe to take surface temperature mea- surements of items like rotating, hard-to-reach, electrically live, or dangerously hot targets. For preventative maintenance tasks, they cut measurement time to almost zero with the ability to take a surface temperature reading in less than one second.
