Trillium 360 Vault

Summary

Our new line of Trillium 360's give you full bandwidth coverage for global seismology and teleseismic monitoring with a single instrument.

Why the Trillium 360 Vault?

  • Very broadband, exceptional performance that meets GSN operational requirements
  • Extended low frequency range useful out to beyond a 10 000-second time period
  • Able to resolve below Peterson's new low-noise model (NLNM) down to a 300-second time period
  • Wide dynamic range with a clip level of +/-18.2 mm/s up to 10 Hz and 0.17 g above 10 Hz
  • Integrated bubble level, adjustable locking leveling feet
  • Automatic motorized re-centering, can be remotely initiated
