Equipment in S2
The section S2 owns a number of instruments that cover a wide range of geophysical methods. A large part of is was commercially retrieved, but some were self-developed, partly based on available . Die Sektion Geoelektrik und Elektromagnetik verfügt über eine Vielzahl an Geräten, die sich über die große Breite der vorgehaltenen Methoden erstrecken. Dabei ist ein großer Teil der Instrumente kommerziell erworben, einige davon wurden aber selbst entwickelt, teils auf der Basis verfügbarer Bauteile.
