Machine

High-voltage holiday/pinhole detector

Use

Coating integrity testing, quality assurance

Industry

Marine, oil & gas, infrastructure, tanks

How It Works

High voltage is applied to a brush probe that passes over the coating; pinholes create a spark that triggers an alarm.

High-voltage spark testing reveals pinholes and thin spots in protective coatings before they cause corrosion.
