Trillium 360 Posthole

The Trillium 360 Posthole provides full bandwidth coverage for global seismology and teleseismic monitoring in a single instrument. 

Trillium 360 PH
  • Very broadband, exceptional performance that meets GSN operational requirements

  • An 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) dow to a 300-second time period

  • A wide dynamic range with a clip level of +/-18.2 mm/s up to 10 Hz and 0.17 g above 10 Hz

  • The lowest magnetic sensitvity of any broadband seismometer
