The Thermal Leak Detector makes it easy to monitor your home's energy efficiency by finding areas that let heat out and cold air in. It's ideal for checking not only outlets, walls, and moldings, but also surfaces that you shouldn't touch, like car engines and other hot areas.
And it's easy to use. Simply aim, depress the trigger, and scan the laser beam across the area you want to inspect. The temperature on your LCD will change and you can easily find those problem areas. The detector also displays temperatures in either Fahrenheit or Celsius on the LCD screen.
