Maddox MPS Portable Reference Anode Electrode S/S – MPS.PRE12M
Are your boat’s zincs (or other) anodes wearing out quickly requiring frequent replacement? Do you suspect its the marina or your neighbor? The only way to determine if your boat’s bonding system is functioning properly is to measure the voltage in the water around your boat. Where to start? First, be sure to clean all bonding connections in your boat with a wire brush and re-attach. Second, you should measure your boat’s electrical potential in the water. To do this, you will need a reference anode and a decent multi-meter!
The Silver/Silver Chloride (Ag/Ag/Cl Reference Electrode is designed to be used to identify the electrical potential generated by metals in water like drive shafts, eye brackets or through hull fittings. Using those results you can determine a vessels optimum level of cathodic protection.
- Quickly and accurately check for signs of galvanic corrosion
- Used efficiently with any good quality digital multi meter
- 12 meter lead

How to check Use the MPS Portable Reference Electrode
Key steps:
- Prepare the electrode: Remove the protective wetting cap from the electrode.
- Disconnect power: Turn off shore power and disconnect onboard batteries for the most accurate readings.
- Position the electrode: Lower the electrode into the water at the center of the transom, aiming for a depth similar to the propeller.
- Connect to multimeter: Attach the lead wire from the electrode to the appropriate input on your multimeter.
- Take measurements: Use a probe to contact the hull at various points, recording the potential readings on your multimeter.
Important points to remember:
- Avoid contact with metal: Do not allow the electrode to touch any metal surface while submerged.
- Read instructions carefully: Always consult the manufacturer’s instructions for specific details on using your MPS PRE12M.
- Calibration: Regularly check the calibration of your electrode to ensure accurate readings.
- Safety precautions: Follow standard electrical safety procedures when working with electrical equipment.
