AEMC Instruments 2135.56 - 6422 3-Point Digital Ground Resistance Tester - 50k Ohm w/150 ft KIT


The AEMC Instruments Digital Ground Resistance Tester Model 6422 performs 2-pole and 3-pole ground resistance measurements. This direct reading tester is auto-ranging, so it automatically seeks out the optimum measurement range. The Model 6422 is easy to use - simply connect the leads, press to measure, and read. The large LCD also indicates low battery status, overrange, and lead reversals and is powered by 6 x AA rechargeable NIMH batteries.
