EMFAD UG 12/4       NEW!!!

Geophysical Exploration Systems

About us:
EMFAD - GmbH&Co.KG is a geophysical company which was established 1993. In cooperation with different universities, the business-originators have employed their long-time experience in the use of geophysical electromagnetic procedures for the development of the EMFAD - Detector, (EMFAD = ElectroMagnetic FieldAnomaly Detection). The world-wide success of the EMFAD UG 12, which is produced since 1997 for geophysical ground-examinations, will be continued with the successor instrument EMFAD - UG 12/4.

  • Data processing: With software EMFADO- SCAN for 2D and 3D presentations, interpretation, modeling, documentation and printing.
  • Data export: For further processing and documentation to Microsoft -EXCEL and SURFER from Golden Software.

Data output/exchange from EMFAD -UG 12/4 to a Notebook (or PC) via RS-232 interface for data processing with the evaluation- and presentation software EMFAD -SCAN.

The EMFAD - measuring method is based on the evaluation of electromagnetic field data caused by anomalies in the subsoil from:

  • Conductive materials, such as metal, pipes, barrels, cables, reinforced concrete, electrolytic effluents, etc.
  • Irregularities like cavities, graves, faults, shafts, ground fills, deposits, caves, tunnels, landfills.

The EMFAD - Technology has been successfully deployed in practice under various different climatic and geological conditions from professionals as well as from hobby researchers. Fields of application predominantly are archeology, geophysics, geology, hydrology and treasure locating in very different application areas as surveying industrial waste sites and waste deposits, building lots, mining areas, street-construction sites, military practice sites and other soil investigation.
