Assemblies and methods for monitoring cathodic protection of structures

A method to install a cathodic protection coupon monitoring assembly, the method comprising:

• passing lead wires from a coupon assembly through a rod cavity of a probe rod, the probe rod including a rod member extending between a proximal rod end and a distal rod end, the distal rod end at least partially including the rod cavity, and the coupon assembly including:
• a first fitting,
• an electrically conductive test coupon adjacent the first fitting,
• a reference electrode, and
• a second fitting positioned between a distal end of the coupon assembly and the electrically conductive test coupon, the second fitting including a fitting chamber configured to be at least partially filled within electrolyte, and the reference electrode at least partially inserted within the fitting chamber;
• engaging the coupon assembly with the probe rod;
• inserting the probe rod and the coupon assembly to a preselected depth;
• withdrawing the probe rod from the preselected depth so that the coupon assembly remains at the preselected depth;
• and
• connecting the lead wires to an electrical junction in communication with a testing device configured to facilitate measurement of potential differences detected by the coupon assembly.

• inserting the probe rod and the coupon assembly to one or more of a preselected depth or a preselected distance relative to a structure;
• withdrawing the probe rod from the preselected depth;
• leaving the coupon assembly at the one or more of the preselected depth or the preselected distance during the withdrawal of the probe rod;
• and
• connecting the lead wires to an electrical junction in communication with a testing device configured to facilitate measurement of potential differences detected by the coupon assembly.
