VES EVS Vertical Electrical Sounding Equipment Geophysical Resistivity Meter

 

 

WDDS is a new generation intelligence multi-electrode resistivity instrument. It can automatically measure and memorize voltage, current, apparent resistivity, and SP parameter.

 

 

Application of VES EVS Vertical Electrical Sounding Equipment Geophysical Resistivity Meter

  • Underground water detector

  • engineering geology inspecting as dam base exploration and flood

  • metal exploration

  • city geophysical exploration

  • railway and bridge inspection

  • geothermal 

Features of VES EVS Vertical Electrical Sounding Equipment Geophysical Resistivity Meter

  • Transmitter and Receiver is all in one, it is portable and flexible.
  • Super storage capability ---- more than 150000 times. (including voltage, current, resistivity, relative error, SP, array constant, measuring point and so on)..
  • Quality monitoring----- Automatic display electrical resistivity and relative error between current measuring result and last measuring result. Memorizing the measuring result and relative error at the same time..
  • Array constant table----Memorizing 30 different array constant, avoiding repetitive input, input number can invoke polar distance or reset.
  • Grounding electrode check----- Monitor MN electrode potential dynamic variation with grounding electrode resistivity check.
  • Electrode array -----Calculate eight kinds of ordinary constant of field electrode array automatically, or input special electrode array constant directly.
  • Super-low power consumption -----CMOS large scale integrated circuit, stand-by current low to 30mA, automatic cut-off when the stand-by time overtime.
  • Automation-----Automatic SP compensation by single-chip microcomputer (SCM), gain adjustment, filtration and signal enhancement.
  • Safeguards-----Over-voltage protection, over-current protection, high-voltage opposition protection, AB open-circuit protection, power-fail protection.
  • On-line operation----RS-232 serial interface on-line work with other microcomputer.
  • RS-232C port can communicate with other computers.
  • Self-diagnostic function ----- Self-diagnostic function to fault location and main damage device.
  • All sealed constitution---Water-proof, dust-proof, long life and so on
