TRILLIUM COMPACT

COMPACT VAULT SEISMOMETER
The world’s best-selling broadband seismometer, the small
highly portable Trillium Compact is available in several
configurations to best suit your deployment
Class-leading performance
The Trillium Compact is extremely simple to deploy with no mass lock and no masscentering required. The exceptionally small size significantly reduces the time and effort
required for site preparation and installation. Continuous quality data are available withinminutes of deployment with no requirement for further intervention.
The Trillium Compact 120s combines the superior performance of a broadband
seismometer with the installation convenience of a rugged geophone. The 120s
instrument incorporates a symmetric triaxial force feedback sensor design witha response flat to velocity from 120 seconds to 100Hz.
The Trillium Compact 20s features the same force feedback sensor design with aresponse flat to velocity from 20 seconds to 100Hz. The 20s instrument features anindustry-leading tilt tolerance of 10°, making deployments very fast and efficient invarious surface conditions. Several base foot options are available for different terrains.
The Trillium Compact Posthole models are also available that feature a stainlesssteel enclosure and waterproof connector ideally suited for downhole deploymentsof up to 300 meters..

Benefits• Low-noise broadband

seismometer performance
combined with the handlingand installation convenienceof a geophone• Ultra-low power consumption(180 mW) allows for smaller
power systems and higher
station reliability.

• Exceptionally small size

significantly reduces the timeand effort required for site
preparation and installation• Quick and easy to deploy withno mass lock, no mass centeringand a wide tilt range• Integrated web server facilitates
instrument management

Optional transport case doubles
as thermal insulating cover forsurface deployments.
