| Seismic Recording System |
| High Resolution Versatile Seismic Recording system can be used for all seismic surveys |
|
The DAQ3-3 is the third generation of portable seismograph systems. The system can be configured as a stand-alone monitoring system, a refraction system or a distributed seismic reflection system. The DAQ3-3 has been designed for temporary or long term installations and can be monitored continuously or periodically, locally or remotely. External clock discipline via GPS Module, VHF/UHF radios or Wire enables usage in any environment. |
