Integrated monitor Touch screen display Wireless Seismograph 24 / 96 channels - 24 bit Top-range seismograph equipped with 24-48-72-96 embedded channels for active and passive seismic surveys. X824S basic configuration integrates 24 channels and can be expanded with 24 channels modules, without external boxes, up to maximum 96 integrated channels. Instrument has a PC with 10” monitor and operative system Windows 10. Management of all settings, acquisition parameters, recording and visualization of recorded data, are performed sequentially and in an intuitive manner by means of the operative system installed on the instrument, which includes also a guide with step by step instructions for the realization of the most common surveys. High flexibility together with high dynamic range make X824S the ideal solution for every kind of active and passive seismic survey: surface seismic investigations such as Refraction, Reflection (P and S waves), M.A.S.W. , Re.Mi. , E.S.A.C., bore-hole surveys such as Down Hole and Cross Hole, stand-alone passive station H.V.S.R. and vibrational monitoring. With particular regards to seismic methodologies, 24 channels module allows the use of a single cable with 24 takeouts that, together with integrated battery pack, reduces the number of accessories to bring on site.
