Extech 382357 Clamp-on Ground Resistance Tester

Model 382357 Clamp-on Ground Resistance tester enables non-contact measurements of ground conductors without the need for auxiliary ground spikes. Comes with 9V battery, resistance check plate, metal storage case, and user manual. Optional NIST Certificate of Calibration with data available (Model 382357-NIST).

Measures resistance from 0.03Ω to 1500Ω and True RMS AC Leakage current from 0.2mA to 30.00A. It features programmable datalogging with 116 points, programmable hi/lo alarms, 0.9” jaw size, self-calibration when powered on, and verification resistors to confirm the accuracy of the meter. Cat III-300V.

Clamp-On Ground Tester simplifies ground resistance measurements on multiple-point ground systems. Use to verify the resistance of cellular and communication tower ground grids, check utility transmission systems and grounding rods, perform maintenance on electrical transportation systems. Ideal for verifying ground systems in sub-stations, factories, and office buildings.
