SMALL SAIL AND MOTOR SHIPS - METAL AND POLYESTER HULLS Corrosion is your n°1 ennemy!
Galvatest detects electrolysis before it is too late...

In addition to steel and aluminium hulls, S-Z drives propulsion devices, outboards, propeller shafts, pods, hydrojets and others immersed metal equipments, in particular those of polyester hulls, are in a state of constant danger of corrosion. Faulty anodes and electrical leaks* lead to costly material losses. By measuring the "corrosion potential" of immersed metals, Galvatest is the simplest and the most reliable way to monitor the effectiveness of protection provided by anodes and detect the unwanted presence of harmful leakage currents from aboard or ashore. European leader in its field, Galvatest gives boaters and professionals the means to effectively protect themselves against underwater corrosion and its disastrous consequences.

* They follow a metallic path to the sea resulting in destruction of metals and/or paint blistering.

Galvatest Sensors

Galvatest mini dipping sensors are Ag/AgCl reference electrodes allowing, when combined with a high impedance multimeter, to obtain a precise value of the corrosion potential of metal hulls and any immersed metals. Their sintering manufacturing technology makes them highly reliable.

Galvapen Kit

PRE-S

The Yachting Galvapen kit is intended for all owners of pleasure boats, sail/motor, and any kind of hull material: GRP, steel, aluminium. It allows you to test the level of cathodic protection and easily ensure the absence of leakage currents, which generate destructive electrolysis, regardless of their origin, whether on board or at the dock.

Professional Kits

Galvatest kits are autonomous complete control systems intended for crews and professionals. Their regular methodic use is recommended to maintain integrity of a boat afloat by checking the efficiency of its anodes and ensuring there are no corrosive leaking currents from aboard or ashore.

Wood or polyester hulls: mind the sail-drives!

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!

Steel or aluminium metal hulls: a well-known evidence!

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...

Electric propulsion: a new challenge!

The gradual implementation of electric propulsion will pose new challenges for builders and yachtsmen. A formidable enemy of submerged metal equipments, electrical energy, now available on board in large quantities, involves best practices in terms of wiring, earthing management and integrity controls...
