ZH480 Portable Corona Detection Camera — UV+VIS Dual F.O.V. Lens

The ZH480 is a professional-grade portable bi-spectral corona detection camera from UVIRSYS. Its built-in dual field-of-view lens system switches instantly between wide-angle and telephoto modes, enabling both close-range substation inspections and long-distance transmission line surveys — with one lightweight 1.8 kg device.

  • Dual F.O.V.: 13.3°×10.6° wide / 5°×3.75° telephoto, menu-switchable
  • Solar-blind UV detection: 240–280 nm, accurate in full daylight
  • UV+VIS overlay accuracy: 0.5 mrad
  • Up to 5 photon counting boxes for quantitative discharge analysis
  • Weight: 1.8 kg | SKU: ZH480
Dual F.O.V. Lens — Wide & Telephoto in One Camera
The ZH480’s integrated dual F.O.V. lens eliminates the need to carry or swap optics in the field. Switch instantly between a 13.3°×10.6° wide-angle view — covering 4× more area at the same distance — and a precise 5°×3.75° telephoto for distant targets like transmission towers and wind turbine blades. One camera, every inspection scenario.

Solar-Blind UV Detection in Full Daylight

Operating in the 240–280 nm solar-blind spectrum with a high-precision cutoff filter, the ZH480 delivers zero false positives from solar interference. Detect weak corona and partial discharge signals accurately — in bright daylight, at any time of day.

Quantifiable Discharge Analysis

With up to 5 configurable photon counting boxes and 0.5 mrad UV+VIS overlay accuracy, the ZH480 goes beyond detection — it quantifies. Trend discharge intensity over time, prioritize repairs by severity, and generate professional reports with embedded image and MP4 video data.

Lightweight & Built for the Field

At just 1.8 kg, the ZH480 is designed for comfortable one-handed operation across long inspection routes. A 5″ sunlight-readable transflective LCD, one-button simplicity, hot-swappable batteries, and no external cooling make it the ideal tool for demanding outdoor utility environments.

ZH480 Portable Corona Detection Camera — UV+VIS Dual F.O.V. Lens

The ZH480 from UVIRSYS is a professional-grade, portable bi-spectral (UV+VIS) corona detection camera featuring an innovative built-in dual field-of-view (F.O.V.) lens system. It delivers exceptional versatility, efficiency, and precision for predictive and preventive maintenance of high-voltage electrical equipment — without ever swapping lenses in the field.

Imagine completing a full substation sweep and a distant transmission line inspection in a single outing, with one lightweight 1.8 kg camera in hand. That’s the ZH480 advantage.

Dual F.O.V. Lens — One Camera, Two Perspectives

Traditional UV corona cameras force you to choose between wide-angle and telephoto optics. The ZH480 eliminates that tradeoff with a single integrated dual F.O.V. lens, switchable instantly via the on-screen menu:

  • Wide-Angle (13.3° × 10.6°): Increases inspection area by up to 4× at the same distance — ideal for bushings, insulators, and switchgear.
  • Telephoto (5° × 3.75°): Sharp, detailed imaging of distant targets — transmission lines, towers, and wind turbine blades.

Superior UV + VIS Performance

  • Solar-Blind UV Detection: 240–280 nm spectral range with high-precision cutoff filter — accurate corona detection in full daylight, zero solar interference.
  • Overlay Accuracy: 0.5 mrad UV+VIS image fusion for precise defect localization.
  • Photon Counting: Up to 5 counting boxes for quantitative discharge intensity analysis — single or multi-area.
  • Display Modes: UV+VIS combined, UV only, or VIS only on a 5″ sunlight-readable transflective LCD.
  • Recording: High-quality image and MP4 video capture with embedded data for professional reporting.

Key Specifications

  • UV Spectral Range: 240–280 nm
