electrical resistance probe

1. n. [Enhanced Oil Recovery]
An instrument used in a corrosion testing to determine metal loss. The probe 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 resistance probe is also called an electrical coupon.
Alternate Form: corrosion coupon
