Holiday Detectors for Protective Coating Inspection
Holiday detectors are used for holiday testing, also known as continuity testing, to find pinholes, voids, porosity and other defects in protective coatings.
Find coating film defects that may not be visible
Help prevent corrosion, leaks and premature coating failure
Used on tanks, pipelines, vessels and buried structures
Inspect to Your Standards:
General Holiday Testing
NACE SP0188
Holiday detection of new protective coatings on conductive substrates.
Metal Substrates
ASTM D5162
Discontinuity detection in nonconductive protective coatings on metallic substrates.
Pipeline Coatings
NACE SP0490
Holiday detection of fusion-bonded epoxy coatings on steel pipelines.
The Elcometer 236 Holiday Detector provides high voltage porosity testing to detect pits, flaws, holes, etc. in a wide variety of non-metallic coatings.
The Elcometer 236's convenient carry case allows the probe handle and accessories to be attached to the front making the Elcometer 236 holiday tester ideal for field, site or laboratory inspection.
The Elcometer 266 revolutionizes high voltage DC testing of coatings porosity detection making it safer, easier and more reliable than ever before.
The Elcometer 266 holiday detector can be used to test porosity on coatings up to 7 mm (275 mils) thick and is ideal for inspecting coatings on pipelines and other protective coatings.This holiday tester features a built-in voltage calculator which will determine and set the correct test voltage based upon the test standard and the thickness of coating being tested.
The Elcometer 280 is a 'stick type' holiday detector which has been designed to make pulsed DC high voltage holiday detection safer, easier and more reliable than ever before.
Using state of the art electronics, the Elcometer 280 allows users to inspect coatings - without connecting the earth return lead to the component substrate - ideal for inspecting large surfaces and pipelines. Using the wide range of probe accessories users can detect porosity / holidays in coatings up to 25mm (1") thick.
The Elcometer 280 uses the high voltage pulsed DC technique to detect holidays in coatings - even if the coating is damp, dirty or slightly conductive.
