Meridian 120 Posthole
High performance all-in-one seismograph for down-hole installations.
Exceptional performance for a variety of downhole installations
Marrying the sensor to the digitizer and recorder, this all-in-one seismographfeatures the latest generation Trillium 120PH class seismometer technology mounted on a leveling system inside a stainless steel pressure vessel. Inherent in all Trillium seismometers, the Meridian PH provides low power consumption, remote mass centering, and a robust no-mass lock design. The Meridian PH is also available for Polar environments.
Meta data you can trust
Instrumentation configuration is made easy with an intuitive user interface. Once configured, the Meridian PH builds its own metadata. With the digitizer and sensor housed in a single unit, dataless seed volume is internally built and guaranteed to be correct every time.
Efficient array management
Simplified site visits and logistics: reduced “touch time” makes it easier to manage your resources. Combining proven technologies in a single package keeps it simple with less to forget, less to integrate.
Direct bury installation provides consistent performance gains.
