Types of Holiday Detectors
1. High Voltage Holiday Detector
A High Voltage Holiday Detector is commonly used for inspecting thicker, non-conductive protective coatings. It uses electrical potential to identify coating discontinuities on conductive surfaces.
Key Uses:
- Thick pipeline coating inspection
- Underground pipeline testing
- Industrial storage tank inspection
- Heavy-duty protective coating testing
2. Low Voltage Holiday Detector
A Low Voltage Holiday Detector typically uses a wet sponge testing method. It is suitable for inspecting certain thin, non-conductive coatings applied over conductive surfaces.
Key Uses:
- Thin-film coating inspection
- Metal surface coating testing
- Industrial equipment inspection
- Protective paint testing
