"PCE-TC 29 is a pyrometer camera used for visual inspection and non-contact IR temperature measurement. Ideal for industrial use in electrical, mechanical, and building installations (such as in the auditing of machines, engines, or heating, ventilation, and air conditioning (HVAC) systems), this affordable thermal imager captures and saves 60 x 60 pixel IR resolution images to the included MicroSD memory card.Locate hot and cold spots with ease by using the thermal imager's picture-in-picture overlay capability. The imager's built-in color camera captures the real-life visual, while the integrated thermography camera acquires the IR temperature signature. The IR temperature signature is superimposed in increments of 25% over the real-life color camera visual, so both images are viewed simultaneously."
