What Is An Orp Sensor

Unlike a ph sensor an orp sensor measures the ratio of oxidized to reduced forms of.

What is an orp sensor. Orp is measured by a probe in a small sample of flowing water usually next to your chemical controller. Orp is measured using an electrochemical sensor called an orp or redox sensor. It is a potentiometric measurement from a two electrode system similar to a ph sensor. The oxidation reduction potential orp sensor measures the ability of a solution to act as an oxidizing or reducing agent.

This orp meter is easily recognisable from the others because it s the only one that is not black. Similar to to ph sensors the most common type of orp sensor is a combination sensor with a measuring electrode and a reference electrode. Oxidation reduction potential or orp is a measurement that indicates the degree to which a substance is capable of oxidizing or reducing another substance. Basically a signal is sent between them which determines your oxidation and reduction potential.

The higher the reading the more oxidizing it is. The oxidation reduction potential of water is measured in the range of 2000mv and is accurate to 5mv. A positive orp reading indicates that a substance is an oxidizing agent. The rate of electron transfer is measured in mv and read as orp.

Orp is measured in millivolts mv using an orp meter. 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. Sometimes it is also referred to as a redox measurement. 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. An orp sensor consists of an orp electrode and a reference electrode.

The ph and orp sensor is combined due to the fact that they work similarly. 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. 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.
