ZH480-PRO is a compact, high-sensitivity bi-spectral camera for corona discharge detection. It supports accurate measurement and long-distance inspection of transmission lines, substations, railway networks, and high-voltage laboratories. The device offers telephoto FOV (10°–1.25° H / 7.2°–0.9° V) for remote targets, automatic alarm based on photon-count threshold, and quantitative recording with GPS and environmental sensors.
