Development of the Redox Probe Field Technique

15

TL;DRAbstract

A description is given of a field technique developed to obtain oxidation-reduction potentials of soils through the use of a probe. The results of all tests with this probe indicate that redox potential can be an extremely useful tool for corrosion engineers. The instrument is rugged enough for use in the field but sensitive enough to find even small indications of bacterial corrosion. A comparison is made between redox data and the following items: (1) Pipe-to-CuSO4 profile study, (2) Four-point soil resistance survey, (3) pH readings, (4) Earth current readings, and (5) Seasonal variation. 2.4.2
