BLACK+DECKER TLD100 Thermal Leak Detector

About this product

Heating and cooling accounts for about 50% of your energy usage, but the average house has enough leaks and drafts to equal a 1 sq. ft. hole. Cut down on wasteful spending with the help of the Thermal Leak Detector from Black and Decker. This convenient tool features an infrared sensor that finds these leaks along walls, molding, ductwork and more. Auto color change provides quick, intuitive feedback, showing users where to caulk and insulate.
