Ridgid has released a line of thermal imagers. The line includes the RT-3, RT-5x, RT-7x and RT-9x models. The imagers are ideal for locating electrical problems, hidden moisture, overheating motors, insulation voids and thermal bridges, officials say. Every model has SuperResolution, which doubles the image resolution for saved images. Some models are compatible with the Ridgid Thermal app, which allows creating and sharing reports as well as view, edit and analyzing captured images.
