The terms are interchangable in meaning: ORP = Oxidation-Reduction Potential (Redox)
The term ORP is more commonly used for bioprocess applications in Europe and the U.S.
The term Redox is more commonly used for industrial chemical process applications in the U.S.
The ORP potential of a media is related to the overall availability of electrons in the media, specifically the ratio of positive and negative ions in the solution. Note that ORP measurements vary significantly with changing pH.
