DC Pinhole/Holiday

DC Pinhole/Holiday

A high-voltage DC holiday detector is a quick and effective means of locating defects and faults in non-conductive coatings over conductive materials. The detector unit is used in conjunction with a suitable electrode and passed over the entire coating area. Weak spots, faults and pinholes are located by the completion of an electrical circuit through the defect to the conductive material beneath; triggering the detector unit’s alarm.

DC pinhole/holiday detectors have a wide range of applications across numerous industries; from locating leaks in flat roofs to integrity-testing corrosion resistant coatings on pipelines; from testing cable insulation to locating faults on waterproof bridge-deck coatings.

Description
Specifications

Buckleys manufacture a wide range of electrodes and accessories for our detectors; designed
to make the testing process as effective and as quick as possible. In addition to this, we offer a
range of kits which have been created with a specific purpose in mind and include a combination
of accessories which are optimised for that application; such as our PHD Pro’6S, PHD Pro’30S and
PHD Pro’40S kits.

Buckleys PHD Pro’ pinhole/holiday detectors offer unsurpassed accuracy and reliability in a compact, battery-powered portable unit.

The highly versatile PHD Pro’ range is available in three outputs; the PHD Pro’6 has an output voltage range of 500V to 6kV – ideal for testing thinner coatings of between 4μm and 570μm, while the PHD Pro’30 can test coatings thicknesses up to 14.4mm and the PHD Pro’40 can test thicknesses up to 25.6mm.
