How to Choose the Right Holiday Detector for Coating Pinholes

Learn how to select the proper holiday detector to find pinholes in coatings and prevent corrosion failures. This video explains the differences between low and high voltage detectors, coating thickness considerations, and how zinc-rich primers or retained solvents can affect readings. Understand when to use low voltage detectors for thin coatings, high voltage for thicker coatings, and important safety tips to avoid ignition hazards in flammable environments. Protect your coatings and ensure long-lasting asset performance. 0:22 Why choosing the right holiday detector matters 01:02 What a holiday (pinholes) is and how detectors work 01:17 Low voltage vs. high voltage holiday detector guidelines 01:46 Zinc-rich primers and their impact on detection accuracy 02:02 Ensuring coatings are fully cured before testing 02:14 Safety considerations in flammable environments
