AEMC Instruments 2135.50 - 6471 3 & 4 Point Digital Ground Resistance Tester KIT w/300 ft Leads


The AEMC Model 6471 ground resistance tester is a portable measurement instrument designed to measure ground resistance with 2 clamps (no auxiliary rods), Bond/Connection Resistance (2-Pole and 4-Pole Kelvin sensing), Ground Resistance (3-Pole or 4-Pole), Ground Coupling Resistance, and Selective Ground Resistance, Soil Resistivity (Wenner or Schlumberger method). The Model 6471 measures from 0.01 to 99.99 kOhms and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current. The model 6471 is also extremely easy-to-use! Simply connect the leads, select the test mode, press Start and read the results! The Model 6471 is CAT-IV rated to 50V and is over voltage protected to more than 250 ACV against accidental connection to live circuits. The voltage is also displayed on screen. In the event of a system fault, the Model 6471 can withstand 250 ACV.
