Product Description

Multi- function Terrameter Geophysical Survey Equipment

Introduction

This geophysical survey equipment is multifunction, it will measure various parameter such as voltage, current, apparent resistivity, apparent polarizability, natural potential, self electric gradient, half decay, attenuation, excitation ratio, deviation, metal factor, ground resistance and voltage decay curve.

The geophysical equipment with Intelligent control,the curves and data will display in screen on real time. It will work for 1D VES (Vertical Electrical Sounding), 2D Electrical Resistivity tomograph and 3D IP imaging.

The Geophysical Equipment will work together with resistivity cable, electrode, software. 2 person work together, one is operate instrument, and another for cable array.
