STS-1 (legacy product)


The iconic STS-1 was the very first broadband-seismometer available and it made broadband-seismology possible. Its performance was legendy and only recently it was outperformed with the introduction of STS-6.

We don't support STS-1 anymore.


  • Begin of broadband-seismology
  • Set of two horizontal and one vertical sensor and detached electronics.
  • Extensive thermal and barometric shielding necessary
  • Manufactured between 1981 and 1991
