Welcome To Seismic Source Company

Seismic Source Company is a manufacturer of seismic instruments and data acquisition systems. Its products are used in a broad range of applications: Seismology, Structural Monitoring, Seismic Site Evaluation, Civil Engineering, Gas and Oil Exploration, Industrial Vibration Monitoring.


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.
