The Fluke 65 is the ideal tool for measuring surface temperatures of hard-to-reach, electrically live, or dangerously hot devices. If you work with AV equipment or lighting equipment, you can probably think of a couple items that fit that description; maybe you've burned your fingers more than once. With the Fluke 65 infrared thermometer, you'll never have to wonder, “How hot is it?” again. This compact, battery-driven device provides quick, noncontact temperature measurement.

Using the Fluke 65 is simplicity itself: Push a green button, and it's on. Point it at the suspect device (a bright laser beam helps you target accurately) and take a reading on the thermometer's clear, backlit screen. Readings typically take less than a second, and data can be stored for later reference. The thermometer is accurate within a tenth of a degree for temperatures up to 200 degrees Fahrenheit. At higher temperatures, it is accurate to one degree. It works from 40 degrees below zero to 932 degrees Fahrenheit. If the temperature of the device you are checking is fluctuating, the Fluke 65 will give a minimum/maximum range. The Fluke 65 runs on alkaline batteries (supplied), which the company says will last for 4,000 measurements.

Fluke Inc. is based in Everett, Wash., and is well-regarded as a producer of industrial test instruments. To learn more about the thermometer, including where to buy it, visit
