Weighing less than 300g and sized a palm only, IR528 is the smallest and lightest thermal imaging system available in the market. It features instant-on imaging, accurate and simple intuitive control, thus can be used as either hand-free viewer or a portable monocular. Operating in thick smoke, dense fog and total darkness, no doubt it is the ideal system for firefighting, field vision and 24-hour security. And it costs you the minimal amount for ownership.
