Some companies to check with are:
NGI, Elk Grove Village IL 1-708-437-6444
AEMC Instruments, Boston MA 1-800-343-1391 www.aemc.com
Both companies make / distribute ground (soil) resistance testers
Good Luck!

Subject: Clamp-on Ground Resistance Testers
Hi members,
I have a quick question here for you, just we need to
know your experience
comments regarding to the so-called Clamp-on ground
resistance tester.
We need such kind of tester to take measurements of
grounding resistance in the
field, it seems such type of Clamp-on tester very
useful for us, because we need do it on the building
roof and the standard procedure is almost impossible
to implement.
Some of our applications are:
* Measure ground rod and small grid resistance;
* Measure resistance and continuity of grounding loops
around pads and buildings;
* Conduct quick field checks;
* Measure leakage current flowing to ground or
circulating in ground loops, etc.
Does anyone have any recommendations, comments,
suggestions, brands, specs..etc...for such tester...?
Thanks in advance.
Leslie
