Elcometer 280, 236, and 266 Holiday Detectors

Elcometer is a leading manufacturer of holiday detectors, also known as voltage indication testers or holiday testers. These devices are used to identify defects in protective coatings on pipelines, tanks, and other structures. These defects, known as "holidays," are areas where the coating is not present and the underlying substrate is exposed to the environment. Holiday detectors help ensure that coatings are applied consistently and effectively, and can detect holidays that may not be visible to the naked eye.


Elcometer offers a range of holiday detectors, including the 280 Pulsed DC Holiday Detector, the 236 DC Holiday Detector, and the 266 Holiday Detector. Here is a brief overview of each of these devices:

Elcometer 280 Pulsed DC Holiday Detector

The Elcometer 280 Pulsed DC Holiday Detector is a portable, hand-held device for detecting holidays in coatings with a dry film thickness of 50 mils (1.27 mm) or greater. It uses a pulsed direct current (DC) voltage, which allows for high sensitivity and the ability to detect small holidays. The device has a voltage range of 1000 to 30,000 volts and a current range of 1 to 10 milliamperes, and is suitable for use on a variety of surfaces, including steel, concrete, and wood.


Elcometer 236 DC Holiday Detector

The Elcometer 236 DC Holiday Detector is a portable, hand-held device for detecting holidays in coatings with a dry film thickness of 50 mils (1.27 mm) or greater. It uses a direct current (DC) voltage, which provides reliable and accurate results with minimal false positives. The device has a voltage range of 1000 to 20,000 volts and a current range of 1 to 10 milliamperes, and is suitable for use on a variety of surfaces, including steel, concrete, and wood.

Elcometer 266 Holiday Detector

The Elcometer 266 Holiday Detector is a portable, hand-held device for detecting holidays in coatings with a dry film thickness of less than 50 mils (1.27 mm). It uses an alternating current (AC) voltage, which allows for high sensitivity and the ability to detect small holidays. The device has a voltage range of 50 to 500 volts and a current range of 1 to 10 milliamperes, and is suitable for use on a variety of surfaces, including steel, concrete, and wood.


In conclusion, the Elcometer 280, 236, and 266 holiday detectors are reliable and accurate tools for identifying holidays in protective coatings. Each device is designed for use on specific types of coatings and surfaces, and offers a range of voltage and current levels to suit different applications and requirements.
