ABEM 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.
Robust and durable design
ABEM Terrameter SAS 1000 is designed for demanding field work in tough conditions and has been well proven during years of field work in all parts of the world. Its cast aluminium casing is rugged and robust, yet light and easy to carry, and meets the IEC IP 66 standard.
High power current transmitter
ABEM Terrameter SAS 1000 comprises a powerful built-in constant current transmitter that runs on either a clip-on battery pack or an external power source.
High quality receiver
The input channel is galvanically isolated and combined with a high resolution receiver which provides an excellent dynamic range.
An intuitive user interface makes the ABEM Terrameter SAS 1000 easy to operate and measured data is exported and handled with the SAS Utility Software which also manages protocols and export of data to the most common interpretation software formats.
