GeoBox
The digital seismograph GeoBox is a high-performance instrument especially suitable for recording signals for seismological and geophysical surveys such as the Horizontal/Vertical Spectral Ratio (HVSR).
The communication protocol is public, software plugins exist for SEISMOWIN, SEISLOG, SEISCOMP and EARTHWORM. The instrument’s features include extreme ease of use, reliability and low power consumption.
The SR04 GeoBox is an instrument based on our SADC20. Designed to reach the highest performance combined with electrodynamics sensor like 4.5Hz to 0.1Hz (SS-45/20 o SS-10/08/02/01) embedded in the instrument, it can be equipped with or without GPS for the synchronization with other instruments.
The instrument is designed for passive seismic survey or structural vibration survey. Compact and reliable, it is ease to use and in few minutes is possible to deploy and set for an acquisition with our software Log-MT (Suite SeismoWIN). The elaboration is even easier with our GeoExplorer HVSR (Suite GeoExplorer).
APPLICATIONS
The GeoBox is designed for engineering vibrational survey, modal analysis ed HVSR.

The Digital Array (DA) is a modular high-speed real-time network system composed of a number of mono-, bi- or triaxial
seismographs connected in a high speed bus. An interface connecting to a PC or a complete SL06 recorder equipped with a GPS provides accurate synchronization to the bus and data recording and processing feature. Up to 8 nodes can be connected on the same branch. Several branches can work as data source over the standard TCP/IP bus and SeedLink
protocol.
