NACE Article on a Portable Test Station for Collecting & Transmitting Pipe-to-Soil Data

The M. C. Miller Company has collaborated with Terry Hurt, a 30-year veteran of the Southern California Gas Company on the design of a unique portable test station, termed the CP Hunter, that allows structure-to-soil data to be monitored over extended periods of time, either using a data-logging device or a remote monitoring system.  A unique aspect of the design, which is described in the May 2009 issue of NACE's Materials Performance journal, pages 20-21 (http://www.mcmiller.com/pdfs/NACE%20CP%20Hunter%20MAy%202009.pdf), involves the use of a water delivery system which makes the unit particularly well-suited for the unattended monitoring of structure-to-soil voltages in dry soil conditions in which conventional portable reference electrodes may not function optimally.  Pipeline polarization decay, or growth, behavior and local interference monitoring would be potential application areas for the CP Hunter portable test station (http://www.mcmiller.com/cp%20hunter.aspx).
