The ERT 1557 is a high specification ground bond tester.

Suitable for use on 110 v, 230 v and three phase electrical systems, this special lightweight unit provides accurate earth electrode resistance measurement without disconnecting the electrode. It can also be used to measure soil resistivity. (read more)

Winter ground resistance testing is now possible with the Sterling 2301 ground resistance tester. The stakeless method involves simply clamping the instrument around the ground rod (or wire) and reading the displayed ground resistance reading. (read more)

Model 6470 performs grounding resistance, earth coupling measurement, soil resistivity and bonding tests. This direct reading tester measures from 0.01 to 99,000Ω, and is auto-ranging, automatically seeking out the optimum measurement range test current and test frequency. Easy-to-use — simply connect the leads, select the test mode, Press-to-Measure and read the results. (read more)

Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The AEMC 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. (read more)

This instrument is designed to maximize testing capabilities in a lightweight, sturdy format. Additional testing capabilities have been added to the tester, to make it a more comprehensive tool for predictive maintenance. As with the other digital testers, the D3R/D6R/D12R's high precision testing capabilities allow data collection in the shop or the field. (read more)
