3731 Clamp-On Ground Resistance Testers
The Clamp-on Ground Resistance Tester Model 3731 measures ground rod and small grid resistance through any season, without the use of auxiliary ground rods.
Check Resistance on Single and Multiple Rods or Grids
Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The Model 3731 simply clamps around the ground conductor or rod and measures the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
The Model 3731 also provides alarm and memory functions. |
