NEW ABEM Terraloc Pro 2 Seismograph

The ABEM Terraloc Pro 2 is a versatile seismograph that can be used with any type of seismic accessory for every possible application.

The next generation seismograph

ABEM Terraloc is adding a new seismograph to the family, which further increases the quality with improved stability and enhanced user experience. Terraloc Pro 2 seismograph is a great companion for almost all seismic applications whether it is as MASW or reflection survey, cross-borehole testing, or a marine refraction investigation.

Typical applications for the Terraloc seismograph instruments are depth to bedrock, bedrock quality, soil stability studies, finding fractures and weak zones, and geological mapping. In all these applications the seismograph is triggered by ground vibrations created by an energy source. Time is then measured accurately until the ground vibrations have propagated through the ground and can be measured by geophones connected to the seismograph.

Enhanced user experience by offering:

  •  A new quad-core computer module  that runs a stable Linux operating system
  • A Wizard mode that facilitates the setup of measurements
  • Improved battery solution (Li-Ion) and power connectors

But above all – an upgraded up-to-date user interface that will improve the user experience of the seismograph. The Terraloc Pro 2 provides improved new functionality in conjunction with the best of the previous version − all wrapped together in one efficient solution.

A standalone system

The ABEM Terraloc Pro 2 is a standalone seismograph and comes with a built-in computer, data storage, measurement channels and user interface. Measurements are conducted using a graphical interface with a look and feel that is familiar. The seismograph is enclosed in an aluminum casing that is rugged and robust, meeting IEC IP 66 classifications so that measurements can be made in all situations and environments.

ABEM Terraloc Pro 2 seismograph is equipped with GPS, WiFi, Ethernet and USB. If needed, the ABEM support team can remotely connect to the instrument, regardless of where the seismograph is situated.

Seismograph measuring seismics, MASW, reflection survey, or cross-borehole testing.

Technical Specifications

Up to 48 Channels

The ABEM Terraloc Pro 2 seismograph can be configured with up to 48 channels in one unit, allowing for many sensors and resulting in high resolution of data. If more channels are needed, several units can be connected to gain more channels. The cutting-edge technology in the design of the measuring channels gives an outstanding resolution of the measured signal both in terms of time and amplitude. The result is incomparable data quality.
