Thermal cameras are great diagnostic tools, but they can be expensive. The new second-generation Flir One is a small camera that connects to a smartphone and uses the phone’s large screen as the monitor. It has a resolution of 160x120, four times that of the previous version. The unit actually has two cameras, one thermal and one regular. It takes a picture with both and has the capability to blend them into a single image, giving solid outlines to the objects in the thermal image. The Flir has an onboard battery, so while it’s operational, there is no drain on the phone power, yet all captured images and video are stored on the phone. Models compatible with Apple and Android platforms are available. Price: $250 / COO: China /flir.com
