Seek Thermal has developed a series of devices that allow you to harness the power of thermal imaging at a much more palatable price range. We will be checking out one of their CompactPro thermal imagers designed to work with your Android mobile phone. This little device connects to your phone via the USB port; and with a free mobile app it uses the screen, processing power, and flash memory of your phone in conjunction with the CompactPro's 320x240 thermal sensor.
