Fluke 1630-2 Earth Ground Clamp

Category: Earth Ground Tester

Quick Overview:

Tag: #fluke #Earth Ground Tester #Fluke 1630-2

Test the grounding components of equipment in hard-to-reach spaces, including areas that are indoors or fully paved and do not permit driving auxiliary test stakes. Stay on line - identify ground loop resistance without the need to disconnect then reconnect the earth electrode from the system.

The Fluke 1630-2 Stakeless Earth Ground Clamp is the kind of high-quality, rugged tool you expect from Fluke. Heavy-duty clamp jaw stays in alignment and in calibration even in every day, on-the-job industrial environments.

Stakeless measurement

The 1630-2 clamp measures earth ground loop resistances for multi-grounded systems using the dual-clamp jaw. This test technique eliminates the dangerous and time-consuming activity of disconnecting parallel grounds, as well as the process of finding suitable locations for auxiliary test stakes. You can also perform ground tests in places that were previously difficult: inside buildings, on power pylons or anywhere you don’t have access to soil to place auxiliary test stakes.
