The new Trillium 120PA version is identical in form, function and performance to the T120P and now is available with the added benefit of fast "one touch" motorized mass centering. Motorized mass centering simplifies seismometer installation and gives customers the option of remotely re-centering the masses via a telemetry connection.

This seismometer is an exceptional instrument with a self-noise within 4db of the NLNM at 100 seconds and below the NLNM up to 10 Hz.

This instrument incorporates the same symmetrical triaxial design and suspension system as the highly successful Trillium 240. The robustness and reliability of the mechancial suspension is well-proven; with over 1000 Trillium units operating in the field, there have been no suspension system failures.

As with all Trillium sensors, the 120PA does not have a mass lock. Instead the T120PA uses a field proven suspension system capable of withstanding the rigors of field handling and transportation. During deployment the sensor requires only manual leveling before operation.
