  • Cathodic protection coupons are a simple, size-specific piece of metal with one or more wires attached and are used for evaluating corrosion control or cathodic protection systems protecting a structure, typically a steel pipeline. These measurements include:

    • Native or unprotected structure-to-soil potentials
    • Structure-to-soil potentials with the CP system energized
    • Structure-to-soil potentials with the CP system interrupted
    • To emulate an “OFF” structure-to-soil potential without interrupting CP current, typically referred to as a “Coupon Interrupt” reading
    • For magnitude measurements of AC current density on a structure with known induced AC issues

    Cyclone-100 Coupon Details

    The "Cyclone-100" steel C.P. coupon is a 100 cm2 "barrel" or cylindrical coupon common in C.P. testing.  The larger surface area of the coupon may provide better coupon-to-soil contact upon burial, which is an important consideration for testing.

    The coupon is mounted inside a durable PVC housing and the Cyclone-100 is provided with a dual length of #12 AWG stranded copper cable with RHH/RHW direct burial insulation, typically green in color.
