AEMC® Introduces two NEW Portable Hand-Held Ground Resistance Testers, Models 6422 and 6424

These new Ground Resistance testers are both economical and feature rich. They are ideal for testing commercial, residential, and light industrial grounding systems. Their innovative design simplifies the process and provides reliable results eliminating confusion in setting it up correctly. A simple one button connect-press-read operation is all that is needed. The Model 6424 is capable of storing and calculating the measurements from the simplified 62% test method and displaying the average and % deviation which is important in determining correct spacing for the test.
