Elcometer 266 Holiday Detector

The Elcometer 266 DC Holiday Detector is a state-of-the-art instrument for detecting pinholes, flaws, inclusions, thin spots, and bubbles in non-conductive coatings applied to conductive substrates. Designed to revolutionize high voltage DC porosity testing, the Elcometer 266 makes inspections safer, easier, and more reliable than ever before.

Capable of testing coatings up to 7.5mm (300 mils) in thickness, it is particularly well-suited for checking pipeline coatings, storage tanks, and other protective systems in industrial environments. This detector is ideal for ensuring the long-term performance and integrity of anti-corrosion coatings.

A key feature of the Elcometer 266 is its built-in voltage calculator, which automatically determines and sets the correct test voltage based on the selected standard and the measured coating thickness. This eliminates guesswork and ensures compliance with international standards while simplifying the testing process.

Engineered for precision and safety, the Elcometer 266 DC Holiday Detector is the ideal solution for reliable high-voltage porosity testing on thick protective coatings.

Current limiting to avoid coating damage:When the Elcometer 266 detects a flaw, and sparks, the current flow reduces to a low level, minimising risk to both the user & the coating;
Automatic voltage calculator: No need for lookup tables, simply enter the coating thickness value and select the standard & the gauge will automatically set the voltage;
Safety hand grip: Ensures that high voltage can only be generated when the handle is being held;
Internal jeep tester: Removing the need for 2 gauges. The closed loop system with internal voltmeter guarantees the voltage output at all times;
Specialised handle design: Extended ribbing on the handle provides an effective barrier between the high voltage and the user.
Rugged and waterproof to IP65: Rugged, waterproof IP65 case is sealed against the elements;
Accurate sensitivity adjustment: Allows use on metallised or slightly damp coatings;
Rechargeable & replaceable battery packs: Battery packs can be charged inside or outside the gauge;
Interchangeable handles: 0.5–5kV, 0.5–15kV or 0.5–30kV adjustable in 0.1kV steps.
