It is a potentiometric measurement from a two electrode system similar to a ph sensor.
What is an orp sensor.
The oxidation reduction potential orp sensor measures the ability of a solution to act as an oxidizing or reducing agent.
Similar to to ph sensors the most common type of orp sensor is a combination sensor with a measuring electrode and a reference electrode.

This orp meter is easily recognisable from the others because it s the only one that is not black.
The orp electrode the principle behind the orp measurement is the use of an inert metal electrode platinum sometimes gold which due to its low resistance will give up.
A positive orp reading indicates that a substance is an oxidizing agent.
Sometimes it is also referred to as a redox measurement.
Unlike a ph sensor an orp sensor measures the ratio of oxidized to reduced forms of.
The rate of electron transfer is measured in mv and read as orp.
Hach s process orp sensors plug n play with hach digital sc controllers.
An oxidation reduction potential orp sensor measures the activity of oxidizers and reducers in an aqueous solution.
Basically a signal is sent between them which determines your oxidation and reduction potential.
The oxidation reduction potential of water is measured in the range of 2000mv and is accurate to 5mv.
The ph and orp sensor is combined due to the fact that they work similarly.
Oxidation reduction potential or orp is a measurement that indicates the degree to which a substance is capable of oxidizing or reducing another substance.
The higher the reading the more oxidizing it is.
The measurement of orp an orp sensor consists of an orp electrode and a reference electrode in much the same fashion as a ph measurement.
This disambiguation page lists articles associated with the title orp.
An orp sensor consists of an orp electrode and a reference electrode.
Orp oxidation reduction potential is a popular water quality parameter that is normally measured as the voltage between a platinum measuring electrode and a reference electrode.

Though orp is classically based on a standard hydrogen electrode she as a reference practical limitations to this approach cause most commercial orp sensors to use an ag agcl reference.
Use the orp sensor to measure the oxidizing ability of chlorine in swimming pools or to determine when the equivalence point has been reached in an oxidation reduction reaction.
Orp is measured in millivolts mv using an orp meter.
