What's in the Box

  • 6472 ground tester
  • 6474 Groundflex adapter interface
  • 500 foot ground testing reels and auxiliary probe
  • Four 5m GroundFlex sensors


The AEMC 2136.03 GroundFlex Field Kit includes the GroundFlex® Adapter Model 6474 and Ground Resistance Tester Model 6472. This is the ONLY system on the market capable of testing ground resistance of individual power transmission tower legs, as well as total resistance without disconnecting the overhead ground wire – this alone is a huge time and money saver, not to mention a major safety improvement.

NOTE: The GroundFlex Adapter Model 6474 can only be used with the Ground Tester Model 6472 Kit 500 ft.

Key features include testing both ground resistance of tower legs (individually and total) and overhead ground wires. This system tests leakage current through the tower legs and tests at frequencies up to 5kHz to profile impedance, which is important to characterize for lightning strikes.

The Ground Tester Model 6472 Kit-500 ft includes meter, rechargeable NiMH batteries, optical USB cable, power adapter 110/240V with power cord 115V US, two 500 ft color-coded leads on spools (red/blue), two 100 ft color-coded leads (hand tied, green/black), one 30 ft lead (green), four T-shaped auxiliary ground electrodes, one 100 ft AEMC tape measure, DataView software, ground tester workbook and user manual on USB stick, carrying bag for meter and carrying bag for kit.

The GroundFlex Adapter Model 6474 includes GroundFlex Adapter Model 6474, four GroundFlex sensors (5m) with twelve color-coded rings, connection lead, two extension leads on H reel (black/green) with color-coded alligator clips, one extra black and green alligator clip, six BNC extension leads, calibration loop, three C-clamps, carrying case with wheels and handle for meters, one inverter 12Vdc to 120Vac 200 watt (vehicle use) and user manual.
