DAQ3-24 CH
High Resolution Versatile Seismic Recording system

The DAQlink III 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 DAQlink III 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.


Field Benefits


Cutting-Edge Technology for Data Quality

Ultra High-Speed 24bit ADC (48,000 samples/sec)

High Resolution Clock

Low Noise & Low Distortion Means Better Data


Designed to Produce and Protect Data

Data Always Stored in Box - No Lost Data

Offload Data While Recording – No Lost Production

Better Data Handling for Superior Production


Versatile Operation

Continuous Recording

Trigger on Time, Data Event or Trigger Input

Different Modes for Different Types of Projects


Modular and Stackable

Combine Units for Additional Channels
Uses Common GPS Module & Network Connection
Use "MegaDAQ" Configuration for Maximum Channels in Minimal Space

Multiple Operation Modes

Operate as Stand-Alone Seismograph - Great for Small Crews
Multiple Units Operating in Concert - Increases Crews Flexibility


MegaDAQ: Multiple DAQ3-24s



A MegaDAQ consists of multiple DAQ3-24s connected via a network. This can be either a wired or wireless network. The network both controls the seismographs and collects the seismic data in real time.
