Why would I want to measure ORP?

FAQ - ORP

1. Q: Why would I want to measure ORP? A: ORP measurements are used to monitor chemical reactions, to quantify ion activity, or to determine the oxidizing or reducing properties of a solution. 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. Here again, is another relative measure for biological oxygen demand; low ORP
