Ideal 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 detector features a built-in voltage calculator which will determine and set the correct test voltage based upon the test standard and the thickness of the coating being tested.

QUICK TIP – HOLIDAY TESTS EXPLAINED:
High voltage holiday detection
A high voltage holiday test is normally used to determine the existence of discontinuities in coating films. The high voltage, or porosity technique, can be used to test coatings up to 25mm (1″) thick and is ideal for inspecting pipelines and other protective coatings. Coatings on concrete can also be tested using this method. There are two types of high voltage holiday detectors – Continuous DC and Pulsed DC.
Continuous DC Holiday Detection
Continuous DC holiday detectors, such as the Elcometer 236 Holiday Detector, require direct connection to the conductive substrate. The Elcometer 236 holiday tester provides the user with complete control of voltage and sensitivity settings and is available in 2 versions- 15kV and 30kV.
Pulsed DC Holiday Detection
Using Pulsed DC holiday detection technology, the Elcometer 280 Pulsed DC Holiday Detector is designed to ensure that the energy is contained within very short pulses, each pulse having more energy than an equivalent continuous DC system. This means that the Elcometer 280 holiday detector can be used to test for holidays over slightly conductive coatings, or dirty or damp surfaces. Using state-of-the-art electronics, the Elcometer 280 holiday detector allows users to inspect coatings – without connecting the earth return lead to the component substrate – ideal for inspecting large surfaces and pipelines. From the two-stage safety switch, bright LED’s, and screen icons signifying when the high voltage is on, to the extended ribbing to protect the user from spark creep, the Elcometer 280 Pulsed DC Holiday Detector sets the standard for high voltage measurement safety.
With a wide range of probes and accessories available, a high voltage holiday test can be carried out on a variety of substrates with a different coating thickness and is suitable for all applications.
Ideal 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 detector features a built-in voltage calculator which will determine and set the correct test voltage based upon the test standard and the thickness of the coating being tested.
