Resistivity Imaging Survey System - GWM00372

FEATURES

High resolution and efficiency resistivity measurement
The system consists of two parts, one is multi-function DC resisitivitymeter and the other is multiplexor. Basing on the basic theory and methods of resisitivity measurement, matching with automatic conversion of electrodes (supply and measure) and high-new techniques imaging system CT, It can be used for high resolution and efficient resisitivity measurement.

Flexible and convenient operations
This instrument can auto-compensate the cases of self-potential, drifting and polarized electrodes by employing a full digital auto-measurement. And the result displays on a large LCD screen which can list a total 14 kinds of method models under the High-Density measurement. At the meantime, the sole measurement has 9 kinds of electrode arrangements and real-time display the measured curves.

Convenient data translation
a. It can store data up to 120000 for one time under the model of high-density measurement.
b. It can store total 4800 of sounding points . Each point includes 22 data. This data can be transmitted to PC for digitized-translation with special software.

Available accessories
The 60/120 channel-detector
The copper electrode with spikes
Extended temperature cables
The overburdened lines.
