The Ring Surface Polarization Coupon (also known as an annular or encircling coupon) is an advanced cathodic protection (CP) monitoring probe. Unlike traditional flat coupons, the ring coupon is designed to surround the pipeline or structure, providing a more uniform current density distribution and minimizing edge effects that can skew potential measurements.
