When vessels are isolated from different electrical potentials, the electrical potential (emf.) is allowed to equalise, resulting in a mass decrease in the metal ion transfer rate (corrosion).

Note: Galvanic Isolators are now recommended in the latest AS/NZS standards.

Several types of monitoring systems are available to suit all vessels. Portable technician kits, 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.

It contains a portable Zinc meter, a reference electrode, a bottle of clean, fresh water and a card explaining both the operation of the monitor and the galvanic series of metals.

Ideal for the professional marine electrician looking for a way to expand into electrolysis prevention.

Plug this probe into into your multi meter for economical electrolysis testing of a boat's bonding system and zinc effectiveness.  

This is a simple and effective testing solution that will quickly determine if a component such as props, shafts or underwater fittings are being  protected by the anode.  Every boat should have one of these inexpensive components.

Documentation also provided.

These clever shaft straps wrap around your shaft and the spring provides a constant electrical connection.  Then connect to your boats bonding wire.  Comes complete with strap, springs, attachment fittings and 40cm bonding connection wire.

Available for UP TO 2 inch, 3 inch, 4 inch and  8 inch shafts. (ORDER THE EQUAL OR NEXT SIZE UP)
