Manual: Theory and Practice of pH Measurement
www.emerson.comdiscusses industrial ORP (oxidation-reduction potential) measurements. Although the determination of ORP is not nearly as common as pH, certain industries make valuable use of the measurement. ... Such sensors are often called combination electrodes. The cell voltage is the algebraic sum of the potentials of the measuring electrode, the ...

www3.epa.govcontrol methods employing oxidation reduction potential (ORP) as an effective stand-in for direct chlorine measurement (Bossard et al., 1995), other sources assert that ORP is an inappropriate technique for this purpose (WEF, 1996). For these reasons, control of dechlorination—particularly dechlorination to zero residual—has been problematic.

www.enr.gov.nt.caenvironment for fish or bugs. In healthy waters, ORP should read high between 300 and 500 millivolts. In the North, we might expect low ORP in waters that receive sewage inputs or industrial waste. How do we measure oxidation-reduction potential? ORP is measured directly in the lake or river water that you are investigating using an ORP sensor.
