Hand-held and lightweight, the Infrared Thermometer Gun with laser pointer emits a beam of infrared light that will instantly 'read'-and display on an LED screen-the surface temperature of most any object. The gun, which is designed to provide a safe and easy way to measure the temperature in hard-to-reach places or moving parts, has applications in the home, farm shop, livestock areas, and even grain bins. Depending on the model, it's powered by a 9- or 12-volt battery, can measure temperature from -25ºF to nearly 500ºF, and can work from up to 40 feet away. (Many optional accessories available.)
