Terraloc Pro 2 seismograph

ABEM Terraloc Pro 2 is a versatile seismograph designed for a wide range of applications including; geological mapping, determining depth to bedrock, bedrock quality, soil stability and finding fractures and weak zones.

it can be configured with up to 48 channels in one unit, allowing for many sensors, creating a versatile instrument capable of collecting high resolution data. If more channels are needed, several units can be connected.

The Terraloc Pro 2 is a standalone system computer, data storage, measurement channels and user interface. Measurements are conducted using a graphical interface with a look and feel that is familiar. The system is enclosed in an aluminum casing that is rugged and robust, meeting IEC IP66 classifications so that measurements can be made in all situations and environments. All types of accessories can be connected to the Terraloc Pro, and solutions can be completely customized to every need.
