Monitoring your Hull potential lets you know the condition of your sacrificial anodes and the rate of corrosion of your hull. The Water REDOX readings will enable you to locate the source of corrosive conditions including Stray DC.

Range mV+/- 1999 mV

The Boat Corrosion and REDOX Meter has both Boat Hull and Water REDOX modes and displays results clearly on a backlit display.

Monitoring your Hull Potential lets you know the condition of your sacrificial anodes and the rate of corrosion of your hull. The Water REDOX readings will enable you to locate the source of corrosive conditions including Stray DC.

The purpose-built meter has an automatic stability indicator which freezes the result when ready. This normally takes around 30 seconds. Simply store the result in the Boat Meter’s memory so that you can track the condition of your hull or the local water conditions . Reviewing this data may help to decide when to replace your sacrificial anodes or to find the source of corrosion. The Micro USB output will allow you to dump the results directly into excel for easy reference and plotting the progress of the corrosion.

Features of the meter include:
  • Long Battery life of over 200 hours continuous use.
  • Easy to use
  • Clear display of the Accurate Hull Potential in mV
  • Automatic stability indicator which freezes the reading
  • Internal storage of your results.
  • Rugged splash-proof construction
  • Powered by 4 x AA Batteries
  • Auto -off Battery life saver
  • Micro USB output to download data to Excel.
  • Boat Hull and Water REDOX Modes

The Boat Corrosion Meter also has a WATER REDOX mode which allows for the subsequent addition of the Platinum REDOX Electrode. This will allow the measurement of the corrosion potential of the water in marinas or any waterway to locate areas of corrosive water. This includes the ability to locate the source or proximity of stray DC. Water potential can also be tested to help detect if there is any extra activity in the water that could accelerate hull corrosion such as stray DC current.

The hull potential for a vessel is a function of its hull material and its underwater metals. Whether it is an aluminum, steel, fiberglass or a wooden vessel, the hull potential shows if the vessel’s underwater metals are protected against corrosion or not.
