The premier ROV cathodic-protection survey system for work-class ROVs The Polatrak® Deep C Meter™ 3000 AD shares the capabilities of the Deep C Meter™ 3000, but also offers some substantial upgrades: The 3000 AD combines the ROV-II™ and Polatrak® EFG readouts into a single new pressure housing that's smaller than before; New programmable, ultra-bright LED displays have brightness adjustments; The 3000 AD features RS-232 (standard ASCII string) digital data output, and the unit is ROV 24V DC-powered, so there's no need to open the pressure housing to change batteries.
