Marina Protection Systems' Anode Meter is used to see what is being sacrificed to ion transfer. Simple tests will determine if your vessel is passively eroding away anodes or corroding propellers, rudders, and suffering from electrolysis. Several types of monitoring systems are available to suit all vessels. Portable technician kits (listed below), fixed LED display units and in a bar graph format for panel mounting. Professional troubleshooters can use this identification system to control earth-leakage and electrolysis issues on all vessels that remain in the water.
