Nanometrics’ commitment to the ongoing improvement of our instrumentation has led to the latest addition in the Horizon series, the Trillium Horizon 360.Trillium Horizon 360

The 360 model brings an even lower noise floor and corner frequency to the exceptionally versatile Trillium Horizon design. This lightweight, easy-to-deploy sensor can be both direct buried at shallow depth or set on a pier. 

Local, regional & teleseismic studies 

The Trillium Horizon is ideal for local, regional and teleseismic studies having a response flat to velocity from 360 seconds to 155 Hz and exceptionally low self-noise. Operators will appreciate the low power consumption, automatic mass centering and robust no-mass lock design inherent in all Trillium seismometers. The Horizon is ideal for instrument pools; it gives you all the versatility you need with a smaller financial investment and less storage space required than purchasing both vault and direct-bury instruments. 

A highly integrated station solution 

When using the Horizon with our popular Centaur digitizer, you’ll have access to a digital leveling bubble through the Centaur GUI. The virtual leveling bubble makes for easy leveling down a dark hole, or once buried, gives you the ability to check levelness at any time.
