The Elcometer 266 Holiday Detector revolutionises high voltage DC testing of coatings porosity detection making it safer, easier and more reliable than ever before.
- the voltage calculator automatically sets the correct voltage from your coating thickness value
- Adjustable Voltage:
- 0.5kV - 1kV in 50V steps
- 1kV to 30kV in 100V steps
- Dual safety switch on the handle to avoid accidental switch on (Grey/orange probe handles only)
- Internal Voltmeter/ Jeep tester ensures that the test voltage equals the selected voltage
- Visual and audible alarms, Bright LEDs on the handle, as well as a loud buzzer, clearly indicate when a holiday is detected
- To change the maximum voltage range, select a different handle; 5kV, 15kV or 30kV DC or 30kV DC continuous
- A wide range of probe brushes and rolling springs available
