Black & Decker's Thermal Leak Detector helps reduce energy costs by finding energy leaks in your home.
You'll instantly identify problem areas around drafty windows and doors, and uncover hidden leaks and insulation "soft spots" around electrical outlets, recessed lights, and along floor molding. When the device hits a cold or hot spot, an LED indicator light changes to blue or red depending on the type of temperature change registered.
Finding and sealing energy leaks can save up to 20% on heating and cooling costs!
