Unique split coupon design permits current-on readings with minimal IR drop error.
Easily fitted to the base of a test station riser.
Potential measurements can be made with portable or permanent reference electrodes.
Model UC-BDG Underground Cathodic Protection Coupon is designed to minimize IR-Drop error in measurements made with CP current on. With this unit, the amount of IR-Drop error included in a current-on measurement will be very small (typically, less than 20 mV) and, therefore, can be ignored in routine measurements. However, since many factors contribute to the magnitude of IR-Drop error at any particular site, it is recommend that installations be evaluated individually.
