AEMC 4620 Ground Resistance Tester Kit

Overview

The AEMC 4620 is a battery-powered digital ground resistance tester kit designed for portable grounding system testing and soil resistivity measurements. This auto-ranging instrument directly measures from 0 to 2000Ω and automatically selects the optimum measurement range and test current. The tester meets IEC standards for mechanical and electrical safety and is designed to reject high levels of noise and interference for reliable operation in challenging field conditions. This kit includes comprehensive test leads and auxiliary ground electrodes for complete 4-point soil resistivity testing.
