GP-2A
Earth Ground
Resistance Tester
Ensures safety and performance
Poor 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.
• Measures earth ground resistance -
3 point (fall of potential) or 2 point tests
• Automatically calculates resistivity -
4 point test
• Automatic voltage readings prevents false
measurements
• Test leads, auxiliary electrodes and software
(available on the website) are included
• Autoranging
• Measurement data storage up to 999 readings
• USB download capabilities with PC software
