Amprobe GP-2A adalah alat ukur grounding dan tahanan tanah (soil resistivity). 

Poor grounding is dangerous and contributes to unnecessary downtime and increases the risk of equipment failure. The Amprobe GP-2A Earth Ground Resistance Tester provides accurate and reliable measurements for ground resistance and soil resistivity to assure the 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.

• 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
