The GEO-S120 broadband seismometer is a product rely on years of experience in designing high precision, low noise, and reliable seismic equipment. Based on a very sensitive capacitive transducer that monitors the position of the seismic bass and a feedback loop that generates signal output proportional to velocity with extended bandwidth 120sec to 80Hz. The instrument has low self-noise so it is ideal for local, regional and teleseismic earthquake recording. No mass lock is required and supports automatic mass centering. The sensor provides calibration input and communication via serial port. The GEO-s120 design is exceptionally versatile, ideal for both direct bury and vault use cases. The seismometer casing is made from hard anodized aluminum or stainless steel.
When combined with our GEOthree or GEOsix datalogger the GEO-S120 provides a true broadband station with low overall power consumption, providing an ideal solution for rapid response applications that require high-resolution data. The GEO-S60 version of this seismometer has equal specifications but the output velocity response is flat between 60sec to 90Hz.
