Elcometer 266 Holiday device can be used to detect pores in coatings up to 7.5mm (300mil) thick. Ideal for inspecting pipelines and other protective coatings.

Elcometer 266 holiday device has a built-in voltage calculator that determines and adjusts the correct test voltage based on test standards and the thickness of the coating under test.


User friendly
The voltage calculator automatically sets the correct voltage from your coating thickness value. There is no need to use lookup tables.

The Elcometer 266 Holiday Detector features a dual safety switch in the handle to prevent accidental opening and special ribs, providing superior protection.

With different arm options to change the maximum voltage range; 5kV, 15kV or 30kV DC or 30kV DC continuous.
