The HeatSeeker incorporates an Auto Hot/Cold Tracker, a technology that automatically pinpoints the hottest and coldest temperatures within a single screen by highlighting both with dual cursors. A quick scan of the Auto Hot/Cold Tracker thus identifies current or potential problems, such as overloaded circuits, inefficient heat transfer, moistureleakage, or fluid distribution for a stuck valve. For accuracy in the field, HeatSeeker captures a digital photo of the subject that is then blended with a full infrared picture to provide added detail to the image under review. Depending on the complexity of the image, the technician can choose to blend the digital photo with 25%, 50% or 75% infrared to better identify suspected components. The digital image and the thermal can also be shown simultaneously in the display. Provided ThermalVision software makes it easy to view, edit or analyze images on a PC.
