MA-1™ Monitored Anode
Product Overview
The MA-1 allows accurate logging of the total number of Ampere-hours delivered by the anode. The time-consuming acts of cleaning an anode and then visually estimating consumption (an inherently unreliable exercise) are no longer required. The unique design of the monolithic isolators used in the system provides 100% life cycle reliability; there are no insulated flange joints to fail. The double armored wires used on all Polatrak instruments ensure full life cycle performance.
Polatrak monitors have an excellent track record of success and are installed on more offshore structures worldwide than any other fixed monitoring system. The system has been applied to all galvanic anode types, platform anodes, flush mount anodes and pipeline bracelet anodes.

Applications
Offshore platform jackets & drill rigs.
Seawater ballast banks on SPAR, TLP, and FSU / FPSO structures.
SPAR center well areas.
Inshore structures, piers, jetties, wharves.
Subsea equipment (when used with SunStation subsea readout).
Offshore pipelines
Main Benefits
Allows accurate measurement of anode consumption and remaining life without interference with the anode.
Gives direct verification of CP design criteria.
Proven reliability; these instruments are installed on many of the worlds premier offshore structures and have been used to write the book on CP design in many emerging offshore areas.
Guaranteed performance; Polatrak instruments come with the best warranty in the industry.
