Product details
GEOtiny 30/60/120s
GEOtiny30/60/120 is a compact miniature digital broad-band seismometer which integrates three seismic and three acceleration channels. It supports high resolution 24bit digitizer, embedded linux OS and GPS or NTP timing. Seedlink server ensures reliable real time data telemetry while large storage volume ensures long period local data recording. The instrument has very low power consumption so it can operate getting powered from a small 12Vdc battery. Due to its small size provides the ability to be buried underground. It supports capacitive transducer sensors and an adaptive analog integrator that allows the user to select between a variety of different sensor corner frequencies, (120sec, 60sec, 30), while the high corner frequency remains high (80, 100, 120Hz respectively) thus covering a very wide range of the seismic band. Design simplicity is the great advantage, and it is reflected to the price which is only fraction of the common commercial seismometers. The user can deploy even 100% more units than using common seismometers at same cost.

GEO-S120 Broadband Seismometer
The GEO-S120 broadband seismometer is a product relying 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 an output signal 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.
