The Elcometer 266 revolutionizes high voltage DC testing of coatings porosity detection making it safer, easier and more reliable than ever before.


Elcometer 266 Features

266 screenshot 1
  • Voltage calculator automatically sets the correct voltage from your coating thickness value

No need to use look up tables. Enter the test standard and the coating thickness and the gauge will automatically program the correct voltage.

266 screenshot 2
  • Voltage adjustable using the keypad - no need for screwdriver: 0.5kV - 1kV in 50V steps, 1kV to 30kV in 100V steps

Sensitivity to current can be manually preset or automatically adjusted by the gauge for partially conductive coatings.

  • Internal Voltmeter/Jeep tester ensures that the test voltage equals the selected voltage

The closed loop system ensures that the generated test voltage is accurately measured and continuously controlled, regardless of climatic conditions.

266 probe handles Interchangable probes handles are available, 5kV, 15kV and 30kV DC Versions

2-stage safety switch ensures that if the Elcometer 266 handle is not gripped, the handle will switch off.

266 ribbing
  • Specialised ribbing provides superior protection while an optional second hand grip is ideal for two handed use

To the user and has been specifically designed to meet standard EN61010. High voltage testing has never been safer.

266 speaker The speaker on the gauge clearly emits a ticking noise to indicate that there is voltage at the handle.
266 screenshot 5 A loud audible alarm is activated when a spark is detected. The beep volume can also be adjusted to ensure it can be heard - even in noisy environments.
