Why Choose AEMC® Ground Resistant Testers?

We know it’s essential for you to have the ability to properly measure ground resistance to prevent costly downtime due to service interruptions caused by poor grounds. That’s why we offer one of the largest selections of easy-to-use ground resistance testers.

Pioneers of Innovation

We pioneered the use of clamp-on ground resistance testing and we regularly review and improve the features of our instruments so you can expect AEMC ground resistance testers to be the highest quality, the most complete package, and the simplest way to learn about and ensure ground integrity.

Our revolutionary Clamp-On Ground Resistance Testers will save you time and money with the ability to measure resistance without disconnecting the ground system.

We developed and introduced the only ground tester capable of testing energized transmission towers (Model 6472). It can also test ground resistance of individual power transmission tower legs (as well as total resistance) without disconnecting the overhead ground wire.

Widest Selection of Ground Resistance Testing Instruments

Whether you perform a simplified 2-Point, a more complete 3- or 4-Point Fall-of-Potential test, a soil resistivity test, or a touch potential test, AEMC® has the right instrument to fit your application.

Accredited Ground Resistance Testing Seminars

Our experts understand the processes for earth resistance testing as referenced in the IEEE Standard No. 81. and we want you to confidently understand it too. We conduct accredited one day ground resistance technical training seminars throughout the country. Our course, comprised of both class and field training, will give you all the information you need to understand proper sizing and testing of grounding systems.

Private Seminars & Demonstrations

We also offer personalized private seminars. Have questions on how to use AEMC® Ground Resistance Testers? We're happy to provide a demonstration with our technical experts. Contact us at (800) 343-1391 or email us at sales@aemc.com

  • Ground Resistance Tester Model 6416 (Refurbished)

    Cat. #2141.01
    Range 0 to 1500Ω, Alarm, Frequency selection, 300 measurement storage
    The Ground Resistance Tester Model 6416 measures ground rod and grid resistance and impedance without the use of auxiliary rods. Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting or de-energizing the ground system under test. The Model 6416 simply clamps around the grounding electrode or conductor and measures the resistance to ground.

  • Ground Resistance Tester Model 6417 (Refurbished)

    Cat. #2141.02
    Range 0 to 1500Ω, Alarm, Frequency selection, 2000 measurement storage, Bluetooth
    The Ground Resistance Tester Model 6417 measures ground rod and grid resistance and impedance without the use of auxiliary rods. Clamp-on ground resistance testers can be used in multi-grounded systems without disconnecting or de-energizing the ground system under test. The Model 6417 simply clamps around the grounding electrode or conductor and measures the resistance to ground. Includes Bluetooth for connecting to a computer running DataView, and an app for communication with an AndroidTM device.
