The AEMC 4620 4-Point Digital Ground Resistance Meter measures soil resistivity and ground resistance. Measures from 0? to 2000? with an auto-ranging feature to automatically seek out the optimum measurement range. Resists vibration, shock, and drops up to par with IEC standards. Denies high levels of interference to ensure accurate measurements.
