- Since the electrode potential of antimony metal is a function of the pH of the soil (or solution) that the metal is contacting, a measure of the soil (or solution) pH level can be obtained by determining the potential difference (voltage) between an antimony electrode and a second electrode of known “fixed” electrode potential.
- The etched scale on the side of the Antimony Electrode allows the electrolyte (soil or solution) pH level to be assessed based on the potential difference measured between a copper/copper sulfate reference electrode and the Antimony Electrode.
- The Antimony Electrode is supplied with operating instructions regarding how to perform a potential difference reading and how to determine the pH level of the soil (or solution) under test (please click on the “Instruction Manual” for information).
Note: The copper/copper sulfate reference electrode (such as an RE-5C Electrode) is required for the potential difference test is not included and would have to be purchased separately.
