Geophyscial Surveying Instrument Wenner and Schlumberger Array Electric Resistivity Survey Meter 2D Electric Profiling 3D Electric Resistivity Imaging System



Geophyscial Surveying Instrument Wenner and Schlumberger Array Electric Resistivity Survey Meter 2D Electric Profiling 3D Electric Resistivity Imaging System is to determine the distribution range, buried depth, and electrical conductivity of the underground electrical anomalous object by observing and studying the distribution rules of the underground current field artificially established. Since it electrical method injects fast pulse current into the ground and superimposes the observation of the underground current field distribution, its observation accuracy and resolution are extremely high.

Features:
(1) The electrode layout is completed at one time, which not only reduces the failure and interference caused by the electrode setting, but also lays the foundation for the rapid and automatic measurement of field data;

(2) Effectively carry out scanning measurement of multiple electrode arrangements, so that a wealth of geological information about the structure characteristics of the geoelectric section can be obtained;

(3) Field data collection is automated or semi-automated, which not only has a fast collection speed (about 2-5s per measurement point), but also avoids errors due to manual operation;

(4) Some instruments can preprocess the data and display the profile curve shape. After offline processing, it can also automatically draw and print various results;

(5) Compared with the traditional resistivity method, it has low cost, high efficiency, rich information, and convenient interpretation. Exploration capacity has been significantly improved.
