A New Technique for Rapid and Continuous Measurement of Redox Potentials
1975
Linebarger, R. S. | Whisler, F. D. | Lance, J. C.
A new “salt bridge” technique for the rapid and continuous measurement of redox potentials at various depths in multiple soil columns, utilizing only one calomel electrode, is described. The method was compared with a previous technique where a reference electrode was placed in each of 8 soil columns, containing a total of 42 platinum redox probes. A least-squares best fit statistical analysis indicated that the new technique yields redox potential measurements as accurate as those of the previous method. Several other features of the salt bridge technique make it advantageous for use both in the laboratory and in the field.
