Ground Resistance Tester, 4 Point

4-Point Ground Resistance Testers for Sale

The units are distinctive earth ground testers that can perform all four types of earth ground measurement. Specifically, some testers are able to measure earth ground loop resistances using only clamps – called Stakeless testing. This method doesn’t require the use of earth ground stakes or the disconnection of ground rods.

•3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes
•Selective testing – without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clamp.
•Stakeless testing – innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance.
