  • 2 * 1000 V/(m/s)
  • 0.0083 to 50 Hz
  • surface or borehole

The KS-2000M is a BROADBAND SEISMOMETER based on the time proven Model KS-54000. Its small size makes it ideal for portable applications. KS-2000 has a flat velocity response from 120 s to 50 Hz. Different sensitivities, output levels, and low cutoff periods (100s, 60s, 50s, 40s, 30s,20s) can be ordered.

A separate Controller Interface Model CI-2000 is used to speed up the mass centering, which can also be done remotely, from the digitizer. A different version Model KS-2000/SP is available as a general purpose, portable or borehole, three-component, short period seismometer, with low cut-off periods at 5s, 2s or 1s and an upper cutoff frequency at 100 Hz. The future SMART version of KS-2000 identifies itself via a serial interface (Model, Serial Number, and calibration information) and periodically performs mass centering.
