ZH480-PRO Ultraviolet Imager — Precision Solar-Blind UV+VIS Corona Detection
The ZH480-PRO from UVIRSYS is a flagship professional-grade UV imager engineered for high-voltage electrical utilities, industrial maintenance, and R&D laboratories. Combining a solar-blind UV detector with a full HD 1080p visible camera and proprietary PRECISION-ALIGN™ fusion technology, it delivers real-time pixel-accurate overlaid imagery to detect, localize, and quantify corona discharge and partial discharge — long before failures occur.
Imagine scanning a substation in full daylight and watching a UV hotspot appear precisely on a cracked insulator — pinpointed instantly, no guesswork. That’s the ZH480-PRO in action.
PRECISION-ALIGN™ UV+VIS Fusion
The proprietary PRECISION-ALIGN™ engine merges UV hotspots with the HD visible image in real time with pixel-accurate precision. Instantly identify whether discharge originates from a cracked insulator, contaminated bushing, or loose hardware fitting — eliminating ambiguity and accelerating maintenance decisions.
