The Amprobe GP-2A Ground Resistance & Resistivity Tester provides the best solution for avoiding the risks of equipment failure by accurately identifying poor grounding. It measures ground resistance using 2 and 3-wire method and tests ground resistivity using the 4-wire method. Also, the GP-2A tester offers a voltage measurement of up to 460 volts.
This Amprobe ground resistance tester has an auto-ranging feature that prevents false readings and provides accurate results. It can store data up to 999 readings which is a great companion for big projects. Plus, this GP-2A comes with noise voltage detection that promotes an easier testing experience.
The Amprobe GP-2A tester boasts an LCD display with backlight which is great to use in low-lit areas. It uses six 1.5-volt AA or 1.2V AA NiMH rechargeable batteries that provide approximately 500 tests. Weighing 2.2 lbs, this Amprobe resistance, and resistivity tester measures 2.95" L x 6.50" W x 9.25" H.
