Geophysical Survey Instrument Electrical Resistivity Tomography Equipment for Underground Water Detector
Multielectrode resistivity measuring system constitutes of control host machine that uses WDJD-3A multifunctional digital DC resistivity/IP meter and our company's WDZJ-4 Multiplex Electrode Switcher. The system is characterized by the super storage, nicety and fast measurement, conveniental operation, and the data can be processed by normal domestic high density electricity software, this makes the interpretation more convenient and intuitionistic. The system can be widely applied to energy sources exploration and civil geophysical prospecting, railway and bridge exploration, metal and nonmetal mines resource exploration, also hydrological and engineering explorations such as searching groundwater, determining the hidden trouble location of reservoir basement and levee, it also can be used to geothermal exploration.
Main characteristic:
Nicety, high efficiency: in the precondition of good repeatibility, measuring one section concluding 552 points' requires no more than minutes.
Super storage:in the high density mode 1 (only store resistivity parameter), it can store more than 43680 measured values;in the condition of high density mode 2 (store resistivity and electricity parameter),it can store more than 21840 measuredd values. The data will not lose when suddenly power off.
Ground resistance examination: in the field,you may examine conveniently and quickly at any moment if each ground electrode is ok.
Electrode arrangement: the array types are as many as 18 and can be extended. It can be used for o
fixed section scan (electrode arrangement: AMNB,ABMN AMBN,AMN,MNB,AMNB , SPM ,SPMN ,charging M,charging MN), it can also be used for continuous rolling scan measurment for variational section(electrode arrangement:AM ,AMN ,ABM ,AB -MN,MNB , AMN rectangle ,AMNB ,crosshole dipole), where, continuous rolling scan measurement allows measured section any long without adding the total number of electrodes, it is easy for long section survey. Usera can solve actual problem under the condition of low cost and high efficiency.
All the electrode arrangement sections may designate random electrode number as initial one conventiently and neatly.
