Product Overview
The Polatrak V-String electrode by Deepwater Corrosion Services is a low-cost zinc reference electrode designed for offshore platform and pipeline monitoring. The ultra-rugged construction and ease of installation make this a viable tool for CP retrofit monitoring or to supplement other Polatrak monitoring instruments.
Accuracy is ± 0.02V, which is adequate for a general performance monitor.
The electrode wire typically consists of a galvanized steel aircraft cord with a PVC jacket and an over-braid of polyester fibers. This combination makes the electrode virtually indestructible.

Applications
Offshore platform jackets & drill rigs.
Seawater ballast banks on SPAR, TLP, and FSU / FPSO structures.
Risers.
Inshore structures, piers, jetties, wharves.
Inside J-tubes or in tight spaces where CP has to be monitored.
Main Benefits
Low cost and ease of installation allow many more reference points to be sampled.
Low profile and lack of welded attachments allow electrode location in node crotches, inside annular spaces, and on pipelines and risers.
Lack of a copper cable allows the electrode element to polarize any pinhole or small defects in the conductor, keeping the electrode serviceable.
Steel cable can be literally tied like a rope to subsea members and will not abrade, making V-String perfect for low cost monitoring system retrofits.
