Buckleys (UVRAL) Ltd manufacture and market a range of non-destructive test and inspection equipment such as Pinhole Detectors/Holiday Detectors, AC Spark Testers, Wet Roof Leak Detectors, Low Voltage Pinhole Detectors (Wet Sponge Testers).
Buckleys BathyCorrometer®
The BathyCorrometer® is a well-proven inspection tool for measuring the levels of corrosion on sub-sea structures. Light and easy to use, this hand-held unit enables divers to obtain accurate readings of the corrosion potential levels of structures at the point of contact.
The first BathyCorrometer® unit went into rigorous North Sea service in 1971. Customer satisfaction with the performance of BathyCorrometers® has led to specified use, worldwide. The current model retains the features of the original Roxby unit but with the addition of modern electronics. It can also be connected to a Surface Display Unit (SDU), which provides a top-side verification of readings.
BathyCorrometers® are used for polarisation, corrosion and interaction surveys, in particular as part of the commissioning check or inspection of production and drilling platforms; sub-sea pipelines; ships’ hulls; jetties and other marine works.

B-MK5 CORROSION METER
The B5 corrosion meter is a consistent way of determining the corrosion of underwater structures like ship hulls, pipelines, jetties, drilling platform and other marine structures
Buckleys H50-Marine Survey Kit
Originally developed to monitor the hull to sea water potential of yachts, the Marine Survey Kit is currently used by Dover Harbour (one of the busiest ports in the world) to check corrosion of sheet metal piles. The kit, which is quick and easy to use, consists of a weighted Silver/Silver Chloride Half Cell, a plastic cable spool and an accurate multimeter to read the voltages generated. It provides all the items necessary to carry out corrosion surveys of marine structures and works literally by being dipped into the water.
The Half Cell is housed in a PVC body with holes to allow the easy flow of water past the cell and is weighted to help keep it in position. The electrode can be deployed close to marine structures in permanently fixed cages or in a simple PVC cage.
The cell is connected to the cable spool by 75m of CSP 55/015 cable. Two other leads are supplied to connect the spool and the structure to the accurate multimeter. In use, the multimeter is connected to the structure (+terminal) and the cable spool (-terminal). The Half Cell is then lowered into the sea to the desired position. Turning on the multimeter to the DC voltage range will display the corrosion voltage.

Buckleys H29 – Survey Display Unit
The Buckleys Surface Display Unit (SDU) has been designed to provide a remote method of verifying the corrosion voltage readings of the Buckleys BathyCorrometer®. The SDU (which would typically be placed on board a ship or on a platform) is connected to the BathyCorrometer® (being used underwater by a diver) via a robust, two core water-resistant cable of suitable length (supplied separately).
The measured structure to seawater potential is then transmitted from the BathyCorrometer® to the SDU by a 4-20mA signal. The SDU then converts this signal to a direct voltage read-out, providing the corrosion engineer with a quick and easy verification.
It is recommended that the SDU is purchased with the BathyCorrometer® that it is going to be used with, as this allows both units to be checked together.
The standard kit includes a mains supply lead, calibration leads from the BathyCorrometer® to the SDU and a comprehensive instruction manual.
Buckleys H3 – BCM Checker
Specially designed to verify the accuracy of the electronics inside the BathyCorrometer®, the BCM Checker is suitable for both Buckleys and Roxby units. Quick and easy to use, it will verify the accuracy of the electronics inside the BathyCorrometer® without breaking the water seal and will also provide a benchmark for recalibration. The BCM checker consists of a precision voltage reference giving an output of 1.990 volts. The unit should be plugged into the socket in the BathyCorrometer’s® handle, and the other lead should be connected to the probe. With the BCM checker switched off, the BathyCorrometer® should read 0.000 and, with the BCM checker switched on, the BathyCorrometer® should read 1.990.
The BCM checker is powered by a 9 volt battery (PP3) and will shut off its output when the battery voltage is low. One LED shows when the unit is switched on and a second indicates when the battery needs replacing.

Buckleys H4 – UCP1A Contact Probe
The UCP1A Contact Probe is a lightweight and versatile instrument, for conducting underwater cathodic protection potential measurements. The unit has been specially designed for use with manned or Remotely Operated Vehicles (ROVs) and is supplied with three metres of underwater cable.
When the stainless steel probe tip of the UCP1A makes contact with the surface under test, the resulting voltage can be read on a suitable high impedance or digital voltmeter. The UCP1A can be used in a wide range of applications, including production and drilling platforms, ships’ hulls, jetties and other marine works.
ROOFING AND ROOF MEMBRANES

Leaks in flat roofs can be located by using Buckleys ‘Wet Roof Pro’ Leak Detector Kit’.  The equipment is suitable for all roofs constructed with non-conductive insulation materials.  A wet surface is necessary for the test to be effective.

Waterproof membranes can be tested for pinholes and porosity by using a High Voltage Detector. For the test to be effective, the membrane must have a conductive backing i.e. PVC on steel, felt on concrete or foil-backed insulation board.
Faults through the membrane can be easily located by passing a high voltage across the surface using a brush or roller electrode. The PD30R  is recommended as it is suitable for membrane thicknesses of 16 microns to 14.4mm or the PD40R which is suitable for membrane thicknesses of 64 microns to 25.6mm. Alternatively, the PHD 2-40 (60 microns to 26mm) or the PHD 1-20 (20 microns to 6.5mm) can be used.
