To be used in conjunction with the 9999 Cathodic protection electrode to measure Hull or Corrosion potentials.

This cable is connected to the opposite terminal of the Measuring instrument (pH or High Impedance Multi-Meter) and the crocodile clip is connected directly to the Boat Hull or metallic object being measured.

The 5 metre coaxial cable has a 4mm Banana plug connector for the Meter (RED Terminal) and a Crocodile Clip for the Hull or Object.

Using the Cathodic Protection BNC Adapter will enable the accurate reading of the Hull or corrosion potential using the QP451 mV meter.
