on request
Item ID: medusa__start


The product was successfully added to basket
Main features:
  • Direct current methods
  • Induced polarization
  • Frequency sounding
  • Stray currents
  • Self potentials

The geoelectrical receiver SGD-EEM MEDUSA is designed to measure values of the electric potential and current for slowly varying signals, as well as to measure the amplitude and phase characteristics of the harmonic components of the periodic signal. It can also be used with external switching device (switchbox) for tomographic surveys.

Application area — geophysical exploration using:
  • Direct current methods
  • Induced polarization
  • Frequency sounding
  • Stray currents
  • Self potentials

There are 2 variants of delivery sets — standard and advanced. The difference is that advanced set includesbunloading with battery and the charger for battery.
