Elcometer 266 High Voltage Holiday Detection: How to Set Voltage & Workflow Correctly
Undetected coating holidays are costly: rework, complaints, corrosion. The Elcometer 266 helps you reliably detect defects – provided it is set up correctly and used in a reproducible workflow.
Quick Overview
The Elcometer 266 is a high voltage DC holiday detector for coating inspection up to 7.5 mm thickness. Its integrated voltage calculator automatically sets the correct test voltage based on standard and coating thickness. Additional features include a dual safety trigger on the probe handle, visual and audible alarms, and an integrated voltmeter/jeep tester principle for voltage monitoring.
