Description

This product is the most innovative & high-tech solution for seismic monitoring networks, developed by TDG. It includes an ultra low noise three component seismic internal accelerometer, which breaks the boundaries of conventional recorders. This digital system offers excellent noise performance and unmatched resolution, providing simultaneous sampled acceleration data through the ethernet interface. The product is equipped with an embedded linux powered single board computer system, easily handling all the connection, configuration, data processing, data transfer, event-handling and storage tasks. The unit offers the best price-performance ratio and the most innovative design of its class.
