What is the difference between a holiday detector and a porosity detector?
A holiday detector and a proximity detector are in essence the same thing. An electrical current is run over the painted/coated steel surface and in the event of porosity or pinhole in the coating (also known as a holiday) the current short-circuits to earth and creates an alarm. With high-voltage holiday detectors this can create a spark – hence the name spark tester.
BlastOne has complete range of coating inspection instrumentation, such as digital coating thickness gauge, CTG, ferrous or nonferrous, surface profile meters / surface profile measuring device, testex tape, dew point meters, and magnetic surface thermometers. There are many spark tester manufacturers which make different configurations of spark tester/holiday detectors – depending on the application and the complexity of the surface that requires testing for porosity in the paint coating
High-voltage spark tester is come with different width bristle brushes or rolling spring probes, which can be used on pipelines
Low-voltage sponge detectors and sponge holiday detectors are also available
Paint inspectors should use caution when using high voltage porosity detectors high-voltage holiday detector
It is important that 100% of the coated surface is tested for pinholes using a spark tester. Where ever a pinhole is located, a repair must be conducted in the paint coating – To ensure long coating life and and low maintenance
Most Holiday Detectors have Regulated direct current pulse voltage outputs
What voltage should I use for holiday detection/pinhole detection on my paint coating?
To determine which voltage I need to use on my spark tester, it is important to refer to the paint coating spec sheet and the relevant standards applicable to high-voltage porosity detection
Protective coatings are used to prevent corrosion on structural steel surfaces, but areas of thin or compromised coatings may not be immediately visible to the naked eye. These defects in the applied coating, known as pinholes or holidays, can adversely affect the longevity of the protective coating.
BlastOne’s offering of pinhole detection instruments are reliable tools in ensuring the quality of the applied coating. The instruments conform to all major industry standards, including NACE, ISO, ASTM, and ACA, for pinhole/holiday detection.
Additionally, the instruments are easy and safe to use and are designed to be easily adapted to measure surface of various shapes and sizes. Various kits and modular tools are also available, allowing the tools to adapt to any application.
