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 147A 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.
