The thermal imaging camera does a really nice job at detecting and recording thermal variables on various media from bituminous concrete to wood. The instrument is very useful for observing/recording thermal images associated with air leaks, electrical charge, moisture, and other sources. By combing the infrared with the visual image you can assess the thermal observation with a recognisable object like a door or electrical fixture. It comes with a handy protective holster, removable micro chip, and usb charge cord. A must have tool for any home inspector/energy auditor.
