Fluke 1625-2 GEO Earth Ground Tester

Brand: Fluke Corporation

The Fluke 1625-2 earth ground tester measures earth ground loop resistances using only clamps, only stakes, or one clamp and stakes.

With the stakeless test method, the Fluke 1625-2 is able to measure earth ground loop resistances for multi-grounded systems using only current clamps.

This technique eliminates the dangerous, and time consuming job of disconnecting parallel grounds, and finding suitable locations for auxiliary ground stakes.

This allows you to perform earth ground tests in places you’ve not considered before, such as inside buildings, on power pylons, or anywhere you don’t have access to soil.
Features
  • A unique earth ground tester that performs 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 Automatic Frequency Control (AFC) to minimize the effect of interference
