Galvatest  detects electrolysis before it is too late...

A multifaceted and complex phenomenon, the potential corrosion of the submerged metal parts of your boat, and more particularly of its propulsion system during prolonged downtime, is detected afloat by the significant modifications of their corrosion potential. Deviously accentuated by electrolysis, it is more than ever your n°1 enemy...

Did you know? Unlike metal hulls, boats made of wood or polyester (GRP) are particularly at risk: as their hulls do not carry electricity, metal propulsion devices are necessarily over-solicited... They represent the only way to the sea for unwanted leakage currents from aboard or ashore!

They are primarily concerned by electrolysis and the regular control of their corrosion potential. Such control is conducted in "real time" on all big ships and is an integral part of formal ABYC (American Yacht and Boat Council) recommendations for all recreational boats in aluminium. Be very careful with your hanging anodes : if they are made of magnesium at sea, they will be likely to destroy your immersed paint work... 

The gradual implementation of electric propulsion will pose new challenges for builders and yachtsmen. A formidable enemy of submerged metal equipments, electricity, now available on board in large quantities, requires best practices in terms of wiring, earthing management and control procedures...

Regular control of metal hulls and immersed equipments corrosion potential is a recommended practice of international standards and major boat and equipment manufacturers. All our electrodes sensors are individually tested. Patented technology. Galvatest is a member of Normandie Maritime.
