Description

TERRAMETER LS 2

The 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 unique electrodes, providing high resolution and impressive depth capabilities. With the use of external electrode selectors over 16 000 electrodes can be connected.

The new ABEM Terrameter LS 2 is available in a number of different configurations to perfectly match your requirements. The new 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, but depending on product package not all need be activated. Product packages range from basic to advanced. Upgrades are made by entering a license code in the Terrameter LS companion software. Future development will include time-limited licenses, making it possible to rent upgrades.

The 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 conditions.

The measurement channels have a new filter design for improved Induced Polarization 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 with conventional IP methods (50% duty cycle), if 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.

GEOREVA has a wide range of land, marine and borehole cables. The built-in field computer in the new 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.

Remote connectivity can allow the GEOREVA 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.
