GD-3C Nodal SeismographTriaxial Broadband Seismic Recorder Seismic Node
What is GD-3C Nodal SeismographTriaxial Broadband Seismic Recorder Seismic Node ?
The GD-3C Node is a small, light-weight seismograph node. Designed for "set and forget" data acquisition, the GD-3C node meets and exceeds all seismograph requirements.
GD-3C Nodal Seismograph is a new generation smart seismic acquisition node used to connect with external land and marsh geophone or hydrophone. It has wireless QC functionality to enable a field deployment tool or mobile phone to check for good status. This includes recording parameters, battery voltage, temperature, remaining data storage, GPS position and quality, connected sensor status and more.
