Meridian Compact PH

The Trillium Compact's small size and portability has changed the way we do broadband fieldwork and now the Meridian Compact Posthole takes broadband to an entirely new level.

Marrying the sensor to the digitizer, this second generation seismograph is the latest development in downhole installations. The Meridian Compact PH is a marvel of miniaturization with no compromise on performance.


  • The Meridian Compact PH seismograph is extremely simple to deploy with no mass lock and no mass centering required.
  • The exceptionally small size and self-correcting leveling system significantly reduces the time and effort required for site preparation and installation.
  • Instrumentation configuration is made easy with the intuitive user interface. Once configured, the Meridian Compact PH builds its own meta data.
  • With the digitizer and sensor housed in a single unit, data-less seed volume is internally built and guaranteed to be correct every time.
