SeaBis System - Exclusively Prevents Electrolysis Corrosion.

Each photograph is a thumbnail, mouse click will change page to a larger image with text explanation.
We have added, for display purposes only, two digital meters as the (upper) analogue meters are hard to see clearly. They are not necessary when SeaBis in normal use
The left meter is anode voltage, the right meter stray current.

The left column is the entire display, the right the expanded upper section so the meters digital display can be clearly seen.
The cloud and deposit in the water is aluminum. Caused by 1 milliamp of stray current for 3 months.

One milliamp (1/1000 amp) of stray current, on a 12 volt boat, causes SeaBis to continually flash red. On large, 24 volt vessels, threshold is double that of 12 volt vessels as they have a larger area over which to spread the stray current so it is not as dense.

There was no change, throughout the entire test to the left meter - anode voltage. Any system using a underwater probe through the hull is measuring anode voltage. Seabis measures the stray current that causes electrolysis corrosion. The SeaBis System eliminates that stray current.

When there is no stray current there can be no electrolysis corrosion.

Note the anode voltage meter does not respond to changes of stray current. It cannot be used to eliminate stray current. SeaBis indicates stray current directly and accurately.
