Product Description
Product Overview
The HD-120 High Precision Holiday Detector is a professional-grade instrument designed for detecting coating flaws and porosity in various industrial applications. Featuring digital display and precise voltage control, this detector ensures accurate inspection of protective coatings.
Working Principle
The detector generates high DC voltage applied to coating surfaces through a probe. When the probe passes over coating flaws, the electrical circuit completes, activating audible and visual alarms while potentially producing sparks at the defect location.
Applications
- Oil and gas pipeline inspection for corrosion protection
- Cable, enamel, and metal tank coating flaw detection
- Shipbuilding and marine industry protective coating inspection
- Petrochemical plants and bridge engineering corrosion layer testing
- Water company pipeline inspection and quality control
