FLUKE 1623 GEO Earth Ground Resistance Meter

Diagnose intermittent electrical problems and avoid unnecessary downtime with the FLUKE 1623-2.  Poor grounding not only contributes to unnecessary downtime, but a lack of good grounding is also dangerous and increases the risk of equipment failure.


Why test grounding systems?

Over time, corrosive soils with high moisture content, high salt content, and high temperatures can degrade ground rods and their connections.  So although the ground system, when initially installed, had low earth ground resistance values, the resistance of the grounding system can increase if the ground rods are eaten away.

The FLUKE 1623-2 is a distinctive earth ground tester which performs all four types of earth ground measurement and offers data storage and download capabilities via USB port.


FLUKE 1623 Key Features:

  • A unique earth ground tester that performs fast, accurate testing with and without stakes
  • Tests 3- and 4-pole fall-of-potential, and 4-pole soil resistivity (with stakes)
  • Performs selective earth ground rod testing (one clamp + stakes)
  • Performs stakeless earth ground rod testing (two clamps)
  • Features IP56 rating for outdoor use
  • World class accessories will simplify and speed up testing time
  • Professional carrying case
  • USB data storage and transfer


Stakeless Testing with FLUKE 1623:

The FLUKE 1623-2 earth ground testers is able to measure earth ground loop resistances using only clamps. With this test method, two clamps are placed around the earth ground rod and each are connected to the tester. No earth ground stakes are used at all. A known, fixed voltage is induced by one clamp and the current is measured using the second clamp. Then the tester automatically determines the resistance of the earth ground rod.
