Elcometer 236 DC Holiday Detector

The Elcometer 236 Holiday Detector provides high voltage porosity testing to detect pits, flaws, holes, etc. in a wide variety of non-metallic coatings.

The Elcometer 236’s convenient carry case allows the probe handle and accessories to be attached to the front making the Elcometer 236 holiday tester ideal for field, site or laboratory inspection.

An accessory pouch, which accommodates the additional rechargeable battery (optional) can also be attached to the soft carry case - thereby extending inspection time without the need for recharging the unit.

  • Robust and fully portable
  • Audio and visual alarms for noisy environments
  • Supplied with a band brush probe
  • Digital display of output voltage or current
  • Adjustable sensitivity
  • 15kV and 30kV options available with fully adjustable output voltage

The Elcometer 236 holiday detector is available in two versions: 0.5 - 15kV and 0.5 - 30kV. Each unit provides the user with complete control of voltage and sensitivity settings.

An Introduction to Pinholes and Holidays – Porosity Detection

Corrosion is caused by two things – a steel substrate and oxygen, while contaminants such as water can accelerate the process. The coating is there to protect the steel from oxygen and contaminants. A flaw in the coating can leave the substrate poorly protected, or in some cases completely exposed.

How to set up an Elcometer Continuous DC High Voltage Holiday Detector

The high voltage method comes in two versions – Continuous DC and Pulsed DC. In this video, we’ll be introducing you to the Continuous DC method, which is used to test non-conductive coatings up to 7.5mm (300mils) thick on conductive substrates.

Testing Coating Porosity using an Elcometer Continuous DC High Voltage Holiday Detector

Setting the correct voltage is vital, as testing with a voltage that is too low could fail to break down the gap between the probe and substrate, missing flaws. While testing with a voltage that’s too high could break down and damage the coating, causing the unit to alarm when there are no flaws, while creating a flaw in the process. Testing with bright blue sparks is a clear sign the voltage is too high, and is probably damaging the coating.
