Oxidation Reduction Potential (ORP)/Redox & Free Chlorine – Myron L Application Bulletin

Application Bulletin WHAT IS ORP? Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium  bisulfate  and  hydrogen sulfide.  Like acidity … Read More

ORP Sensor Technical Education

What Is “ORP”? ORP is an abbreviation for for Oxidation Reduction Potential, also know as REDOX, and is a useful measurement for monitoring and controlling chemical reactions. Oxidation: addition of oxygen/reduction of electrons Reduction: reduction of oxygen/addition of electrons Characterisitics of ORP: Non-specific measurement of total activity mV output allows automated control of chemical reactions … Read More

Treating Water at ORP Speed, Monitoring ORP leads to Successful Treatment

By Mike Ross Oxidation reduction potential (ORP), also known as redox, is the measurement of a solution’s oxidizing and reducing activity. The ORP process can be likened to stock-market activity: whenever one material is oxidized, another material is reduced (for someone to purchase a share, another person must sell that share). Fire is an example … Read More
