Oxidation-reduction potential

Oxidation-reduction potential (ORP), or "redox", indicates the relative capacity of a solution to oxidize or reduce. For example, to minimize biological growth a cooling system is usually treated with an oxidizing biocide such as chlorine, chlorine dioxide, or bromine.

Maintaining the ORP in a designated range will ensure that the proper amount of oxidizing agent is present. At the other end of the spectrum, reducing agents are often used to remove oxygen or other compounds from process streams. ORP can be used to monitor the proper level of these agents as well.

Hydrolab's ORP sensor uses a simple platinum band that donates or accepts electrons to monitor chemical reactions, quantify ion activity, or determine the oxidizing or reducing properties of a solution.

Features:

• The state of the reaction is measured by the potential developed between and inert noble metal electrode (platinum) and a reference electrode (same reference for pH)
• Compliant with SM2580 B

Benefits:

The ORP is greatly influenced by the presence or absence of molecular oxygen. Low redox potentials may be caused by extensive growth of heterotrophic microorganisms. Such is often the case in developing or polluted ecosystems where microorganisms utilize the available oxygen. Low ORP is another relative measure for biological oxygen demand.
