The ultra low power geodetic grade reference receiver. Optional embedded telemetry makes the Resolute Reference the ultimate receiver for remote applications.
A ruggedized version of the Resolute, to extend the temperature range and conditions the Resolute can operate in.
The 151B Observer is a force-balance feedback sensor with available frequency bandwidth from 0.0083 (or 120 s) – 50 Hz. It is ideal for use in seismicity studies due to its low self-noise performance.


The 147 Low Noise model is +/- 4g full scale and provides excellent dynamic range which is useful when used with 24-bit digitizers like the REF TEK 130S Series Data Loggers and the 130-MC recorder.
This flexible and portable broadband seismometer is ideal for portable deployments and rugged enough for long term deployment in local and regional networks.
REF TEK’s latest generation broadband seismic recorder has a 32-bit A/D performance boost and a large dynamic range.
At the core of all seismological science is accurate data. Seismology is a diverse earth science which includes subfields such as assessment of fault line tension, earthquakes and their aftershocks, and global earthquake analysis.
