electrical coupon

1. n. [Well Workover and Intervention]
An instrument used in a corrosion test to determine metal loss. It directly measures the increase in resistance of a metal as its cross-sectional area is reduced by corrosion. At suitable times, once the readings are obtained, these numbers are converted into corrosion rates (mpy). An electrical coupon is also called an electrical resistance probe.
