DAQlink 5 Seismograph
DAQlink 5 is the fifth generation of portable seismograph systems. It can be configured as a stand-alone monitoring system, a refraction system, or a distributed seismic reflection system.
Vscope software controls the seismograph, providing acquisition control, data QC, and file storage. This seismograph utilizes industry-standard Ethernet for command, control, and fast data file transfer.
