The Trillium 120P is an exceptional seismometer having an instrument self noise 4dB above the NLNM at 100 seconds and below the NLNM up to 10Hz.

This instrument incorporates the same symmetric triaxial design and suspension system as the highly successful Trillium 40. The design employs fewer parts than traditional sensors and offers improved temperature stability. The robustness and reliability of the mechanical suspension is well proven: with over 500 Trillium units operating in the field, there have been no mechanical failures.
