Product Description

2D Electrical Geophysical Exploration Instrument with Multi-electrodes

 

 

Introductuon

 

WGMD-3A high density resistivity measurement system (geophysical exploration instrument) is made of WDJD-3A multifunctional digital DC resistivity instrument as the measurement and control host, with WDZJ-4 or WDZJ-120 multichannel electrode converter, the system has the characteristics of large storage, accurate and rapid measurement, convenient operation, and can be easily used with common high density electrical processing software. It makes the interpretation more convenient and intuitive. The system can be widely used in energy exploration and urban geophysical exploration, railway and bridge exploration, metal and non-metal mineral resources exploration, as well as in hydrologic and engineering geological exploration, such as finding groundwater, determining the location of dam foundation and flood control levees, and geothermal exploration.

 

Main features and functions

 

* Accuracy and efficiency: Under the premise of maintaining good repeatability, the measurement time of a 552 points section is generally less than 15 minutes

* Super-large storage: In high-density mode I (only the resistivity parameter is stored), no less than 43,680 measurements can be stored; In high-density mode II (storage of resistivity and current parameters), no less than 21840 measurements can be stored. Power failure is not lost.

* Grounding check: In field work, you can easily and quickly check whether the grounding of each electrode is good.

* Electrode arrangement: Up to 18 device types and extensible. It can be scanned according to fixed section (electrode arrangement is AMNB, ABMN, AMBN, AMN, MNB, A-Mn-B, self-charged M, self-charged MN, charging M, charging MN) and continuous rolling scanning measurement according to variable section (electrode arrangement is A-M, A-MN, AB-M, AB) -MN, MN-B, A-MN rectangle, A-Mn-B, cross-hole dipole), among which, continuous rolling scanning measurement can allow the measurement section to be connected to any length under the condition that the total number of electrodes is unchanged, which is convenient for long section tracking, enabling users to solve practical problems at low cost and high time.

* All electrode arrangement measuring section can be arbitrarily specified section starting electrode number, convenient and flexible.
