GD-1C Earth Pulse Seismic Vivration Mesurement Nodal System
Nodal system is a seismic data acquisition system by using seismic nodes. Compared with traditional cable based seismic systems, nodal technology allows for the rapid deployment, recording, and downloading of seismic data surveys. Besides, it is also light-weight, battery-powered and more easier to install. More and more people choose to use seismic nodals due to its convenience and multiplex functions.
Features:
Functions:
* Reduce the difficulty forseismic exploration production, greatly improve the efficiency andlower the cost for project
* Automatic deploy and retrieve
* Harsh environments
* Greatly improve thedynamic range rather than other equipment
