AEMC 2135.55 Model 6422 Digital 3-Point Ground Resistance Tester
The AEMC Model 6422 (2135.55) is an accurate and efficient digital ground resistance tester engineered for testing commercial, residential, and light industrial grounding systems. Designed for simplicity, the unit features one-button operation and an intelligent interface where the test button turns green once a stable measurement is acquired. This minimizes uncertainty and accelerates field work.
Equipped with an automatic hold function, auto-ranging capabilities, and automatic test frequency selection between 128 Hz and 256 Hz, the 6422 tester simplifies testing procedures while maintaining reliable data output. The large, backlit digital display alerts operators to low battery status, overrange conditions, and lead reversals. With a CAT IV 600 V safety rating and a built-in hazardous voltage indicator, the device prioritizes operator safety during electrical diagnostics.
