Comparación de los detectores de agua y cavidad de OKM

02 de octubre 2018

The name GeoSeeker stands for water detection as well as cavity detection. Both detectors are utilizing geoelectrical principles to measure the resistivity of the underground soil. According to the Schlumberger procedure four electrodes are placed into the ground to determine its resistivity.

Both, the OKM GeoSeeker as well as the OKM GeoSeeker Mini, are utilizing two electrodes to inject electrical power into the underground soil, whereas two additional electrodes are measuring the potential difference (fall of voltage) at specific scan points to calculate the final resistivity value.

Both geoelectrical detectors are able to detect underground objects and structures like:

  • underground water deposits
    • ground water
    • fresh water, drinking water
    • underground watercourse, water veins
  • hidden cavities
    • tunnels, galleries
    • caves, chambers, sepulchers, tombs
  • impervious layers and barriers
