EFG and ROV-II™

Polatrak® EFG probe

The EFG is an electric field gradient (EFG) measurement device that uses two replaceable silver/silver chloride reference electrodes separated by a known distance (13 inches) to provide a contactless method of determining anode activity and of measuring electric fields in seawater. When passing near a structure such as a pipeline, the current density reading can confirm that an anode is properly activated. Intended for use with the Deep C Meter™ 3000AD ROV survey system (shown), it’s the ideal complement to the industry-leading ROV-II™ contact probe.
