Electrotest-EIS-3KM - capacitively coupled resistivity meter

Electrotest-2Rm  Resistivity System

The device consists of transmitter and a receiver with the micro-processor controlled.

Frequency of a signal - 16550 Hz.

Electrotest-EIS-3KM measures the electrical properties of rock and soil.

Data collection is many times faster than systems with application of electrodes.

Within last 6 years it is made and sold to customers about 120 devices of this series.


  • Full dipole-dipole resistivity profiling
  • Measurements on frozen ground, ice, concrete, and other areas where grounded dipole measurements are difficult to make
  • Mode of automatic measurement with the set time intervals
  • Interface: USB
  • Internal storage batteries in transmitter and receiver
  • Internal chargers for the transmitter and for the receiver
  • In the complete set to the transmitter and the receiver are delivered 4 dipole cables
