This article from Thermo Fisher Scientific's Water Analysis Instruments division explains different units for measuring Oxidation-Reduction Potential (ORP) in water analysis. It covers ORP in millivolts (mV), converting ORP to Eh (standard hydrogen electrode potential), and using RmV (relative millivolts) for calibrated readings. The goal is to help users understand and accurately measure ORP in various applications
