Product Overview

The GL-PCS60/120 Wide/Very Broadband Seismograph is an all-in-one seismic observation device integrating acquisition, storage, data transmission, recording triggering and other functions. It is equipped with a 3-channel collector, compact broadband seismometer, data storage unit, network communication module and GNSS timing unit.

It is mainly applied to natural earthquake observation of national seismic networks, stations and regional seismic networks, reservoir-induced earthquake monitoring, mine seismic monitoring, broadband seismic observation for oil and gas exploration, underground structure imaging and other research fields. It is also suitable for scientific surveys including long-term fixed observation and mobile seismic observation.
