UV Imager - Uvolle-VC

1. UV Imager UVOLLE-VC Product Description:

The UVOLLE-VC is a compact dual-channel UV-visible light imager. A full solar-blind dual-spectrum system that enables you to locate, display, and record corona and arc discharges during the day. The UVOLLE-VC model meets the scanning requirements of high and medium voltage electrical equipment such as insulators, bushings, automotive generators, transformers, switchgear, etc. The main difference between VC and SC is that VC can be used to record videos and has an audio microphone interface, allowing dynamic storage and recording.

This UV imager can be used in industries such as mining, petroleum, data centers, heavy industry, electrical, utilities, workshops, etc.

When detecting in darker environments, this model has a distinct advantage: it can turn on the built-in LED flashlight. The UVOLLE-VC can display real-time information on surface partial discharges, show discharges on critical insulation components, facilitate maintenance of potentially damaged parts, extend component lifespan, reduce passive maintenance costs, and provide complete asset management control. The Uvolle UV imager uses patented technology, a highly sensitive solar-blind UV-visible dual-channel detector, and exclusive lenses. With high sensitivity and strong anti-interference capability, it is unaffected by sunlight and has no time restrictions for detection. It can sensitively detect weak UV light emitted by defects amidst background interference, making it an ideal choice for preventive maintenance inspection tools in substations and overhead transmission lines.

2. UV Imager UVOLLE-VC Product Features:

Lightweight and compact: Ergonomic design, one-hand operation. Equipped with a shoulder strap. Turn on, aim, shoot, store video clips and still images.
Easy operation: Simplified operating procedures, direct access to common functions. Control and modify factory settings of the UV imager via joystick and shortcut buttons. Smart menu guidance, supports user customization.
Corona localization: 1 milliradian merging of UV and visible channels, excellent display of emission sources. Visible light zoom and UV enhancement improve detection results.
Large LCD screen: 4.3-inch luxury reflective LCD backlit with 600 nits high definition. Generates clear images even in very bright conditions.
UV photon counting: Counts detected UV photons and displays discharge intensity on the screen, generating research reports.
Integrated flashlight: Built-in LED flashlight for use in low-light conditions, customizable operation.
Built-in video/image recording and playback: Recorded video clips and still images are stored on a removable memory card. Playback is possible by browsing the image gallery.
Built-in technology: DAYCOR built-in technology ensures UV and visible light sensitivity even in full sunlight conditions.
