HomeGeorevaResistivityABEM TERRAMETER SAS1000


ABEM Terrameter SAS1000 is a highly competent Resistivity/IP system suitable for many different types of applications. By measuring both resistivity and IP simultaneously it minimizes expensive field time and it is expandable with a variety of accessories.

From 2023, its production has been stopped by ABEM. The SAS1000 is now replaced by the Terrameter VES / VES MAX.
