Product Details

Amprobe® GP-2A tester measures earth ground resistance with 3-point (fall of potential) or 2-point tests, and automatically calculates earth resistivity (4-point test). Voltage measurement prevents false measurements. Unit automatically applies 3 testing frequencies for the most accurate reading. Holds 999 readings in memory, with RS-232 for download to a PC. Includes test leads, auxiliary electrodes, and software for complete instrument autoranging.

Customer Reviews


Rated 5 out of 5 by 1reviewer.
Rated 5 out of 5 by Great build quality, great functionality I received an Amprobe GP-2A as a warranty replacement for a previous model that arrived without the accessory bag containing all of the connection cables, the comm cable, and stakes. Amrpobe's Customer Service handled the issue like pros and sent me the replacement unit straight away.Using the GP-2A was very intuitive and provided us with highly accurate results for both ground array resistance and soil resistivity. Both of which were very important to us in the design and installation of a fuel handling & storage facility that required lightning protection, a low resistance ground grid, and cathodic protection for buried pipelines. The ability to export the results was icing on the cake.Well done, Amprobe! October 28, 2013
