      Amprobe GP-2A Ground Resistance & Resistivity Tester

      oor grounding is dangerous and contributes to unnecessary downtime and increases the risk of equipment failure. The Amprobe GP-2A Earth Ground Tester provides accurate and reliable measurements for ground resistance and soil resistivity to assure safety and performance of an electrical system. The GP-2A is complete with PC software that allows the user to download critical recorded measurements and to create professional reports for customers.


      Features

       - Measures earth ground resistance - 3 point (fall of potential) or 2 point tests

       - Automatically calculates resistivity - 4 point test

       - Automatic voltage measurement prevents false measurements

       - Automatically applies three testing frequencies for the most accurate readings

       - Test leads, auxiliary electrodes and software are included for complete instrument

       - Autoranging

       - 999 internal memory locations to store measurements

       - RS-232 download to a personal computer
