Polatrak Deep C Meter 3000AD
The Polatrak Deep C Meter, available in the advanced 3000AD configuration, is a subsea cathodic protection (CP) monitoring system purpose-built for ROV-based inspections of offshore and underwater structures.
It measures the electrical potential of carbon steel assets to confirm proper corrosion protection, giving operators the data they need to assess structural integrity and support long-term asset reliability.
Designed for deployment with work-class ROVs, it enables accurate, real-time CP surveys in demanding subsea environments.
Engineered for deepwater operations, this configuration integrates seamlessly with ROV power and camera systems for efficient deployment and clear voltage visibility.
With flexible probe compatibility and digital data output, the Polatrak Deep C Meter supports comprehensive underwater corrosion monitoring programs across offshore oil and gas, marine construction, and subsea infrastructure inspection projects.

Polatrak Deep C Meter 3000AD for ROV-Based Cathodic Protection Monitoring of Subsea Assets
Corrosion doesn’t take a day off underwater. If you’re responsible for subsea pipelines, offshore platforms, or deepwater assets, you know the constant pressure to prove your structures are protected — not just assume they are.
The challenge is simple but serious: you can’t see corrosion happening in real time, and guessing wrong can lead to costly repairs, unplanned downtime, or worse.
The Polatrak Deep C Meter 3000AD gives you clear answers where it matters most — directly at the steel. Mounted to your ROV, it physically checks the electrical protection levels of submerged assets, so you can confirm whether your cathodic protection system is doing its job.
Instead of relying on assumptions or incomplete data, you get real measurements that help you make confident maintenance decisions and protect critical infrastructure before small problems turn into major failures.
Continuous 24V ROV Power Integration with Dual-Channel CP Probe Capability
The Polatrak Deep C Meter, in its 3000AD configuration, is engineered for seamless 24V DC ROV power integration, allowing it to run directly from the vehicle’s power supply through a splice or oil-filled cable connection.
This eliminates the need for internal batteries and removes the operational risk of surfacing the unit mid-project to change power sources — a process that can introduce flooding risks, O-ring failures, and costly downtime.
In addition, its dual-channel housing combines readouts for the standard ROV-II™ tip-contact probe and the optional electric field gradient (EFG) probe within a single 316 stainless-steel pressure housing.
This allows operators to perform both direct steel potential measurements and touchless anode activity surveys from one compact system, freeing up valuable ROV space while eliminating the need to mount and interface two separate meters.
Polatrak Deep C Meter 3000AD with Advanced CP Survey Software and 3000m Deepwater Durability
The Polatrak Deep C Meter 3000AD is supported by advanced Polatrak survey software that logs 100 percent of the continuous data stream during a cathodic protection survey.
Operators can pre-load custom asset points for organized inspection planning, and the built-in Time Machine module buffers the last 30 seconds of data to prevent missed readings during critical probe contact.
This eliminates the need for perfectly timed button presses and reduces human error, while automatically generating clean .csv files for streamlined reporting and documentation.
Built for extreme subsea environments, the system is rated for depths up to 3,000 meters and housed in a rugged stainless-steel pressure housing designed to withstand harsh offshore conditions.
The ROV-II contact probe is mounted on a shock-absorbing T-handle, helping protect the equipment from impact during heavy manipulator handling.
Together, these features ensure reliable performance in deepwater operations while reducing the risk of equipment failure and costly downtime.
Ultra-Bright LED Display with RS-232 Data Output for Reliable Subsea CP Surveys
The Polatrak Deep C Meter features three programmable, ultra-bright LED displays that provide continuous voltage readouts clearly visible to ROV onboard cameras.
Brightness can be remotely adjusted via RS-232 commands, ensuring optimal visibility in changing subsea conditions, whether dealing with intense ROV lighting or dark, turbid water.
This solves the common problem of washed-out or unreadable displays that can interrupt survey progress and delay operations.
At the same time, the system outputs a continuous RS-232 digital data stream in standard ASCII format to the surface for real-time telemetry and secure data logging.
With both digital transmission and always-on visual backup, operators gain built-in redundancy. Engineers can verify survey results against recorded video footage and continue operations confidently even if serial communications are temporarily disrupted.
Field-Replaceable CP Probe Components for Reduced Downtime and Faster Subsea Maintenance – Talk to Our Team Today
The Polatrak Deep C Meter 3000AD, features field-replaceable ROV-II probe components, including nickel-plated stainless steel contact tips and plug-in silver/silver chloride (Ag/AgCl) reference electrode elements.
This design allows subsea survey teams to quickly replace worn or contaminated parts without specialized tools or sending the entire unit back to the manufacturer.
Instead of facing costly project delays or replacing a full probe assembly due to a damaged tip, operators can perform fast, on-site maintenance and keep surveys moving forward.
If reducing downtime and protecting your offshore inspection schedule is a priority, connect with our team to learn how the Polatrak Deep C Meter can support your next subsea CP survey.
