Product Overview: AEMC 6424 Ground Resistance Tester

The Digital Ground Resistance Tester Model 6424 provides effortless 2pole and 3pole ground resistance measurement. This direct reading tester is autoranging and intuitive simply connect the leads, press the button to measure, and receive a clear reading on the large LCD display. The tester also indicates low battery status, overrange, and lead reversals. This unit is powered by 6 x AA rechargeable NIMH batteries, and optional current probe (Model MN72) allows it to measure voltage up to 600V AC/DC and AC current up to 60A. Additionally, the Model 6424 is available in complete Kits (150ft and 300ft).
