When it comes to ground resistance testers, AEMC has always been number one. AEMC offers the broadest selection of digital 3-point and 4-point fall-of-potential ground resistance testers (including soil resistivity testers) and pioneered the clamp-on ground resistance tester.

For fast, easy, clamp-on ground resistance testers that allow (require) you to leave the ground rod or grid connected, see the AEMC 3711 and AEMC 3731.

For traditional fall-of-potential testing with ground stakes, check out the new multi-function AEMC 6470 ground resistance tester. This award winning product does 3-point and 4-point ground resistance testing, soil resistivity tests, bond tests (2- and 4-wire resistance), touch potential & step potential tests and earth coupling measurements!
