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:
There are 2 variants of delivery sets - standard and advanced.
The difference is that advanced set includes unloading with battery and the charger for battery.
