AEMC Instruments 2135.23 - 4630 4-Point Digital Ground Resistance Tester - 2000 Ohm KIT w/300 ft Leads


The AEMC Model 4630 ground resistance tester performs Ground Resistance and Soil Resistivity tests. This direct reading tester measures from 0 to 2000 Ohms and is auto-ranging so it automatically seeks out the optimum measurement range. The model 4630 is rugged, easy-to-use and is ideal for maintenance crews performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests called out in IEC standards. The model 4630 is also designed to reject high levels of interference, so it can be used under difficult conditions such as high stray currents that normally affect accuracy. The model 4630 is powered by 9.6V NiMH rechargeable batteries and also features a built-in recharge circuit, powered from a 120/230V 50/60Hz line, which allows for continuous testing while the unit is recharging.
