Seismograph for active and passive seismic, equipped with 6 channels, 24 bit resolution, extremely compact and easy to use. Instrument is managed through an intuitive application which must be installed on a PC or tablet with Windows operative system connected to the instrument through USB interface. Ideal for standalone passive seismic methodologies such as seismic vibration at time or trigger threshold, non destructive test, surveys on buildings with three-dimensional sensors and HVSR investigations. Management software can be installed on every notebook or netbook and allows to interface with instrument for the management and configuration of recording parameters for all the different typology of seismic investigations. Connection between notebook - tablet and ST6 is made through an USB interface present on instrument panel. Instrument extremely compact dimensions, its reduced weight and quite competitive price, make it particularly ideal to the use in specific situations which require a rugged, reliable and at same time small instrument, easy to transport even in logistically complicated situations. It is possible to connect to ST6 seismograph both 1D (6 channels) and 3D sensors (12 channels), therefore it is particularly recommended also for structural vibrations monitoring.
