What is a holiday detector?
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
