Earth Resistivity Meterby Robert Beck |
|
This is a two-part article that gives the construction details for a device that can measure ground resistivity deltas. Such deltas might indicate buried anomalies such as large stones, compacted regions, or conductive targets. The articles also give a good background on resistivity measurement as well as some of the pitfalls to watch out for. It was published in the January, 1997 issue if Everyday Practical Electronics, a popular British electronics magazine that is owned by publisher Wimbourne Publishing, Ltd. I would like to thank Wimbourne Publishing for giving me permission to post this online version.
