I wish I'd had one of these when I visited a factory and picked up a "just-forged" socket that had supposedly "cooled off." Now I keep this Infrared Thermometer handy as it saves my fingers from severe blisters! It takes the surface temperature of any object in its field of view in one second, without having to touch it! Press the button, line up the desired object with the red laser pointer and read the temperature on the gauge. Detect a clogged catalytic converter, misfiring spark plug, irregular temperature between brake rotors (sticking caliper), weak heating and air conditioning systems or tire temperatures at the track. How about seeing if you have the correct oven temperature, or a refrigerator set way too cold? The list is endless. The incredible measuring range of -76° to 932°F (-60° to 500°C), makes this thermometer ideal for automotive, medical, and food uses. Narrow 11:1 field of view. (That means at 11" away from the object you are measuring an area of only one inch in diameter.) Convenient hand held design that's only 6" long. The LCD display is even illuminated in case you want to find the hot spot at night. Packed with features, and all the Griot's Garage quality at a great price.
