Our most portable seismograph

Meridian is ideal for transportable arrays and many other applications where portability and rapid deployment are important. With low power consumption, no mass lock or mass centering required and the self-correcting leveling system, the time and effort required for site preparation and installation is significantly reduced.

 

Instrumentation configuration is made easy with an intuitive user interface. Once configured, the Meridian PH builds its own meta data. With the digitizer and sensor housed in a single unit, dataless seed volume is internally built and guaranteed to be correct.

 

Our Meridian Posthole digital seismometer combines a Trillium 120 seismometer and a 24-bit Centaur digitizer, mounted on a levelling system inside a waterproof, stainless steel pressure vessel.
