Polartrack II ROV Probe

Polatrak ROV II Probe

The Polatrak ROV II Probe is a cathodic protection (CP) probe designed for inspecting submerged structures using either remotely operated vehicles (ROVs) or commercial divers.

Built for offshore environments, it helps inspection teams measure electrochemical potential and evaluate cathodic protection performance on critical subsea assets. Its rugged, serviceable design and compatibility with the Polatrak Deep C Meter make it a trusted solution for offshore cathodic protection inspections.

Reliable Cathodic Protection Surveys with the Polatrak ROV II Probe

Cathodic protection systems help protect offshore structures from corrosion, but confirming they’re performing properly requires reliable underwater measurements. The Polatrak ROV II Probe gives inspection teams a dependable way to collect electrochemical potential data using either an ROV or a commercial diver.

The probe supports both tip-contact and proximity measurement methods, allowing operators to adapt to different inspection requirements without changing equipment. Whether performing routine CP inspections on offshore infrastructure or evaluating hard-to-access subsea assets, the ROV II provides a flexible solution for collecting dependable field measurements.

Twin Electrodes Help Prevent Costly Repeat Surveys

One of the Polatrak ROV II Probe’s defining features is its twin reference electrode design.

Unlike conventional single-electrode probes, the ROV II takes two independent measurements at every contact point. If the readings differ significantly, operators have an immediate indication that one electrode may have failed, allowing them to verify the issue while still completing the inspection with the remaining element.

This built-in redundancy reduces the risk of unknowingly collecting inaccurate data—a problem that can lead to costly repeat inspections after an ROV or dive team has already left the site. For offshore operators working within narrow weather windows and expensive vessel schedules, having real-time confidence in measurement integrity helps keep projects on schedule while improving overall data reliability.

Integrate with the Deep C Meter for Digital Subsea Readouts

The Polatrak ROV II Probe can be paired with the Polatrak Deep C Meter to provide digital cathodic protection measurements directly subsea. This combination gives operators immediate access to measurement data during an inspection while supporting digital data transfer throughout the inspection workflow.

When used with the Deep C Meter and accompanying survey software, measurement data can also be logged electronically for documentation and reporting. This makes the ROV II Probe well suited for organizations looking to streamline cathodic protection inspections while maintaining clear, consistent inspection records across offshore asset integrity programs.

Built for Long-Term Offshore Serviceability

Offshore inspections often take place far from shore, where replacing equipment isn’t always practical.

The Polatrak ROV II Probe is designed with field serviceability in mind, featuring replaceable electrode elements and a fully replaceable stainless steel contact tip. These components can be replaced as they wear, extending service life while reducing long-term maintenance costs.

The probe’s free-flooding Delrin body is designed for subsea use and requires no onboard battery, simplifying operation and eliminating battery maintenance. Because the same probe can be deployed from either an ROV or by a commercial diver, inspection teams can use a single solution across a variety of cathodic protection inspection workflows.
