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
