MANUFACTURERS OF SPECIALIST TEST EQUIPMENT

DC Pinhole/Holiday DetectorsA 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 accross 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.

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 PD40S and PD30S kits.

We also manufacture electrodes to customers’ specifications as well as offering innovative solutions to unique testing situations or environments.

PHD rangeBuckleys PHD1-20 and PHD2-40 tried-and-tested pinhole/holiday detectors are a firm favourite in several industries. Having been in production for a number of years, the PHD range has proven to be dependable and reliable.

The PHD1-20 and PHD2-40 detectors are suitable for checking coating thicknesses of between 20µm-6.5mm and 60µm-25.6mm respectively and are widely used in the petro- chemical, aerospace, pipeline construction and plastic fabrication industries.

PD rangeBuckleys PD6, PD1-30 and PD2-40 pinhole/holiday detectors offer unsurpassed accuracy and reliability in a compact, battery-powered portable unit.

The highly-versatile PD range is available in three outputs; a 0.5kV-6kV version - the PD6 - ideal for testing thinner coatings of between 4µm and 570µm, while the PD1-30 can test coatings thicknesses up to 14.4mm and the PD2-40 is capable of testing thicknesses of up to 25.6mm.

DCCT rangeThe DCCT is designed to be a static, mains-powered pinhole/holiday detector; ideal for use in automated testing facilities and production lines.

The DCCT’s casing is designed to fit industry-standard mounting racks and is available in four outputs - 1-7.5kV, 2-15kV, 4-30kV and 5-40kV. All variants are available with a test probe handle for manual use or without; for connection to production-line electrodes.

Specifications

Also availableWe are able to make a wide variety of electrodes to suit our clients’ requirements and we can offer innovative solutions to simplify the testing process.

We designed and manufactured this bespoke electrode system to test internal coatings on large-diamteter sections of pipework. The electrode system is connected to a DC pinhole/holiday detector and drawn through pipework. It’s stabiliser mechanism ensures 100% contact with the coating through 360°; ensuring all faults are detected.
