Measures soil resistivity (4-Point). Measures ground resistance (2- and 3-Point) Fall-of-Potential method. This direct reading tester measures from 0 to 2000Ω, and is autoranging, so that it can automatically seek out the optimum measurement range. This kit includes a ground resistance tester with two 150ft color-coded leads on spools, one 30ft lead, two 14.5" T-shaped auxiliary ground electrodes, one set of five spaded lugs, 100ft tape measurer, and a carrying bag.

Rugged and easy to use, this ground resistance tester kit exceeds mechanical and safety specifications for shock, vibration, and drop tests specified in IEC standards. Additionally, this kit rejects high levels of interference, making it ideal for use under challenging conditions, such as high stray currents that affect accuracy.
