Elcometer 266 DC Holiday Detector

The Elcometer 266 revolutionises 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 7.5mm (300 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.
