PHD Pro2 – Pinhole/ holiday detector – pipeline testing kit (0.5kV – 6kV)


The PHD Pro2 range of high-voltage DC pinhole (or ‘holiday’) detectors are ideal for rapid and effective holiday testing of a range of non-conductive coatings and linings for porosity, faults and defects.

The PHD Pro2 caters for a variety of applications and the wide range of accessories and electrodes available allows the PHD Pro2 to adapt to specific testing requirements. The PHD Pro2 is the result of an exhaustive research, development and design programme which brings the latest technology to the instrument along with a complete redesign of the user interface and a large multi-colour display; making navigating its menus easier than ever and the PHD Pro2 the safest, most intuitive and simple-to-use instrument Buckleys have made yet.

The PHD Pro2’s robust and fully-enclosed design comes with an IP65 rating and enables it to withstand the rigours of daily use in challenging environments with ease. † These standards are pre-programmed and are provided for convenience. However, it is the user’s responsibility to ensure that the correct settings are chosen for the intended application of this unit.
