Meridian PH

A high performance seismograph for downhole installations

Marrying the sensor to the digitizer, this all-in-one seismograph provides exceptional performance for a variety of downhole installations; direct burial, shallow or deep cased holes. The MeridianPH features a Trillium class seismometer and a Nanometrics digitizer mounted on a leveling system inside a stainless steel pressure vessel and provides low power consumption, remote mass centering, and robust no-mass lock design inherent in all Trillium seismometers.
