GalvanAlert Shore Power Corrosion Detector

Introducing GalvanAlert, the world's only shore power corrosion detector with reverse polarity indicator. GalvanAlert easily attaches to your existing 30A shore power inlet and cordset to constantly monitor unsafe corrosion activity or a reverse polarity condition. Now you can act before costly damage occurs to your boat.
• Can save you thousands of dollars in potential corrosive damage to your boat
• Detects reverse polarity that can create a shock or fire hazard

How does GalvanAlert work?
GalvanAlert incorporates sensor-based technology that monitors unsafe galvanic or stray current corrosion flowing through the green ground wire of your shore power system.

Why GalvanAlert if I have a galvanic isolator?
Galvanic isolators only protect against galvanic action. They will not block corrosion currents driven by more than 1.5 volts that can be highly destructive to your boat. GalvanAlert will detect such currents so you can protect your boat in instances where galvanic isolators do not.
