pH and ORP Electrodes
What is pH?
Acidic and alkaine/Basic are two extremes that describe substances, usually liquids or chemicals, just like hot and cold are two extremes that describe temperature. A substance that is neither acidic nor alkaline is neutral.
The pH scale measures how acidic or alkaline a substance is. The scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Pure water is neutral, with a pH of 7.0. When chemicals are mixed with water, the mixture can become some level of either acidic or alkaline. Vinegar and lemon juice are acidic substances, while laundry detergents and ammonia are alkaline.
What is ORP?
Oxidation reduction potential (ORP) is an important method for testing water quality. Oxidation occurs when a substance lacking electrons — known as an oxidizing agent — looks for electrons from other substances. On the other hand, substances that have extra electrons to donate are known as reducing agents.
ORP classifies substances as oxidizing or reducing agents and is measured in millivolts (mV) by an ORP meter. A high ORP reading indicates the presence of an oxidizing agent. A low reading indicates a reducing agent. Water pollution levels tend to increase with low ORP readings and decrease with high readings. Scientists consider the ORP of water as an important indicator of pollution levels. Safe drinking water, for example, is an oxidizing agent with an ORP range between +200 and +600 mV. Chlorinated pool water, on the other hand, should have a much higher ORP between +650 and +750 mV.
