Soil redox potential meter

The Soil Oxidation-Reduction Potential Meter (ORP Meter) is primarily used for on-site, in-situ testing of the oxidation-reduction potential of fresh or moist soil, as well as for measuring data such as water (medium) oxidation-reduction potential, pH, and temperature. It complies with the standard “HJ746-2015 Determination of Soil Oxidation-Reduction Potential by Potentiometric Method.”

Oxidation-reduction potential (ORP/Eh) has been widely used as a comprehensive indicator of soil environmental conditions for a long time. It represents the relative degree of oxidizing or reducing properties of a medium and has a significant impact on soil chemical and biological processes. It is an important parameter for understanding soil properties and processes. The higher the oxidation-reduction potential, the stronger the oxidizing property; the lower the oxidation-reduction potential, the stronger the reducing property. A positive potential indicates that the solution exhibits a certain degree of oxidizing properties, while a negative potential indicates that the solution exhibits a certain degree of reducing properties.
