On les présente sous la forme de couples oxydant-réd Understanding Redox Potential Eh and pH as Indicators of Soil, Plant, and Animal Health and Quality Eh, the name for redox potential, is a measurement of the availability of electrons, whereas pH is a measurement of the availability of protons. In order to gain a full picture of the soil’s capacity About Redox (ORP) Sensors Redox (ORP) sensors measure the oxidation-reduction potential—the tendency to gain or lose electrons when a solution comes in contact with a chemical substance. ORP measurements are used to ensure that a solution has been completely reduced or oxidized. LAMBDA REDOX allows the measurement of the Red-Ox potential and the digital transfer of the data to the PC through its RS-485 interface. The measured data can be visualized and recorded for example by the fermentation software SIAM.

Redox potential is a measure of the propensity of a chemical or biological species to either acquire or lose electrons through ionization. Basic Characteristics A species with a higher reduction potential possesses a higher tendency to acquire electrons and be reduced.

Watch The redox potential is the reduction/oxidation potential of a compound measured under standard conditions relative to a standard hydrogen half-cell. A system that accepts electrons from a normal hydrogen electrode is a half cell that is defined as having a positive redox potential; whereas a system that donates electrons to this hydrogen electrode is defined as having a negative redox potential.

Redox Potentials. The redox potential is a measure (in volts) of the affinity of a substance for electrons — its electronegativity — compared with hydrogen (which is set at 0). Substances more strongly electronegative than (i.e., capable of oxidizing) hydrogen have positive redox potentials.
