Resistivity meters

ABEM Terrameter LS2

The new generation of resistivity meter – ABEM Terrameter LS 2 pushes the boundaries by introducing features previously never seen in commercial resistivity meters.

Resistivity/IP surveying is a versatile geophysical method suitable for a broad range of subsurface mapping applications such as groundwater prospecting, mineral exploration, geological mapping and geotechnical investigations. Depending on the application used, system designs of the resistivity meter can vary. ABEM Terrameter LS 2 resistivity meter is available in many different configurations to perfectly match your requirements.

ABEM Terrameter LS 2 resistivity meter introduces a unique software licensing system, making it scalable and easy to upgrade. Every instrument comes preinstalled with all hardware modules and software features ranging from basic to advance. What feature you choose depends on product package since not all features need to be activated. Upgrades are made by downloading a license code from the internet or USB. Future development of the resistivity meter will include time-limited licenses, making it possible to rent upgrades.
