These are pseudo reference electrodes which can be used to monitor cathodic protection systems in concrete and seawater but the potential of the electrode is dependent on oxygen levels and pH. Calibration certificates cannot be provided for these electrodes.
Element type
Zinc to US Military Spec. 18001 K
Potential:
Variable depending on the environment and corrosion reaction of the zinc.
Drift:
less 3mV in 24 hours.
Dimensions:
200 mm long x 25mm diameter Measuring interface >11750mm2
Cable:
Expected life:
More than 50 years in seawater. The functional life of the electrode will most likely to be determined by the life of the associated cables.
