Wireless 5HZ Node Seismograph Short-Period Seismometers Three-Component Seismograph Nodal Seismograph Broadband Seismograph with GPS
The GD-3C seismograph node is multi channel seismograph to connect to multiple sensors. With its internal memory and GPS, the flexible GD-3C node can be deployed anywhere, at any time.
GD-3C Nodal seismometers or nodes are wireless, three-component, short-period (5 Hz) seismometers that weigh six lbs. each.
The technology was developed by Fairfield Nodal primarily for use in exploration seismology, however nodes can be used to record a variety of seismic processes.
