Abem terrameter LS 2

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

Now Guideline Geo is introducing a new unique IP feature using 100 % duty cycle. This means twice as fast data collection and double the signal to noise ratio compared to the conventional IP method (50%) using the same settings.

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

ABEM Terrameter LS 2 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 will include time limited licenses, making it possible to rent upgrades.

Product Brochure

Technical Specifications

User Manual



ABEM Terrameter LS 2 is a standalone solution featuring built-in measurement channels, high power current transmitter, electrode selector, computer and graphical user interface. Surveying techniques range from 1D to 4D measurements. The robust and rugged aluminum casing meets IEC IP66 classification and allows for use in the harshest of conditions.

ABEM Terrameter LS 2 offers up to 12 measurement channels for greater efficiency and productivity in the field. The built-in electrode selector allows for connection of up to 81 electrodes, providing high resolution and impressive depth capabilities. With the use of external electrode selectors over 16 000 electrodes can be connected. Guideline Geo offers a wide range of land, marine and borehole cables.

The measurement channels have a new filter design for improved IP performance. Using a new measurement mode for IP (100% duty cycle), data collection will be twice as fast and have twice the signal to noise ratio compared to the conventional IP method (50% duty cycle) using the same settings.  Utilizing new technology alongside upcoming features in the Workbench processing package from Aarhus GeoSoftware, it will be possible to extract spectral information from time-domain IP data.

ABEM Terrameter LS 2 continues its great heritage of adding advanced and useful features to resistivity meters. The graphical user-interface makes it easy to use and the entire user experience is streamlined for productivity. During measurement, the system gives continuous information of data quality, showing results directly on screen. Multichannel arrays, such as the Multiple Gradient, ensure measurement tasks can be completed quickly.

The built-in field computer in the ABEM Terrameter LS 2 offers increased computing power, an easy to use graphical user interface and connectivity such as USB, Ethernet, Wi-Fi and 3G. The internal GPS supports GLONASS, which improves positioning accuracy. Data is stored on a removable 16 GB microSD memory card, with a capacity of millions of data readings.

The commitment to data quality and productivity does not stop with the instrument, ABEM software can be used for instrument maintenance, simplifying downloading and processing of data before inversion. After the inversion, visualization tools can be used to make the inversed data more presentable and ready for use in a report.

Remote connectivity can allow the ABEM support team to assist with software upgrades, give support or troubleshoot if necessary. This unique feature ensures that the system is always up to date, operating correctly, with the risk of downtime kept to an absolute minimum.

With the new software licensing system the ABEM Terrameter LS 2 is scalable and future-proof, ensuring a return of investment no matter if starting with a basic or advanced system.


  • Optimized for productivity, minimizing field time
  • Outstanding quality of data even in the toughest conditions
  • Measure IP faster and with better quality
  • Basic or advanced measurements, no limitations
  • Rugged and robust – measure anywhere, anytime
  • Remote connectivity allows assistance onsite
  • Scaleable and easy to upgrade

Case Stories

GPR method in the unseiling of Tomb of Christ

GPR plays an important role in the unsealing of the Legendary Tomb of Christ

Thousands of people are visiting the Church of the Holy Sepulchre in Jerusalem every year. This is the place where Christ shall have been buried and resurrected from the dead.
This historical venue needed to be thoroughly investigated to reveal what is hidden under the floor and behind the walls.
