Elcometer 266 DC Holiday Detector
At a glance:
Safer, easier & more reliable testing than ever before
Avoids coating damage by limiting current
Ideal for field, site or laboratory testing
The Elcometer 266 DC Holiday Detector provides accurate detection of pinholes, flaws,
inclusions, thin spots and bubbles in a coating.
The gauge has been specifically designed to revolutionise high voltage DC testing of coatings,
making it safer, easier and more reliable than previously possible.
