DAQlink 4 is the fourth generation nodal seismograph system. Each DAQlink 4 node can have up to 24 channels. Multiple nodes can easily be added to achieve a 1000+ channel Recording System. It can be configured as a stand-alone monitoring system, a refraction system or a seismic reflection system.

Seismic Source’s proprietary Vscope and SrcSig software provide detailed analysis and storage of the seismic signals. This seismograph utilizes industry standard Ethernet communication allowing easy setup for Wireless or remote autonomous Cell Phone operation.
