Global Waters (Redox) ORP sensor is a ruggedreliable ORP/Redox measuring device. The ORP sensor is molded to 25 ofmarine grade cable, with lengths up to 500 available upon request. TheORP sensor’s output is 4-20 mA with a three wire configuration. The ORPsensor’s electronics are completely encapsulated in marine grade epoxy within astainless steel housing (online version has 1-¼ inch PVC x 12 inch pipe nipple,threaded both ends with cap)
Global Water’s PC300 ORP Controller to usethe ORP sensor’s output to control pumps or alarms. In addition GlobalWater offers GL500 ORP recorder adds recording capabilities to the ORP sensor. The GL500 ORP recorder connects to the ORP sensor’s 4-20mA output to recorddata.
ORP stands for oxidation-reduction potential, which is the measurement (inmillivolts, or mV) of the oxidizing or reducing tendency of a solution. Oxidation is the loss of electrons from an atom, molecule, or ion, which may ormay not be accompanied by the addition of oxygen. When a substance isoxidized, its oxidation state increases. Reduction is the net gain ofelectrons. When a substance is reduced, its oxidation state is lowered. Oxidation and reduction reactions always accompany each other. Everyoxidation and reduction reaction can be characterized by a halfreaction, whichprovides all of the chemical substances participating in the reaction (manyhalf-reactions are identified in standard chemistry handbooks or other referencematerials). The ORP of the solution depends on the concentrations of thesubstances participating in the half-reaction. In order to calculate ORPwhen concentrations vary, you must use the Nernst equation. Due to itslogarithmic dependence on concentration and its dependence on multiple solutioncomponents, ORP is typically not a good method for measuring concentration. The best use of an ORP is in monitoring and controlling oxidation-reductionreactions. When an oxidation-reduction reaction occurs, there is usually alarge change in the ORP, which overwhelms the factors that make concentrationmeasurements an issue. This allows you to ensure that an ORP reaction hasgone into completion, and thereby control your application appropriately.
