X824S

MAE srl

New

The X824S is a top-range seismograph equipped with 24 to 96 embedded channels for both active and passive seismic surveys. The basic configuration starts with 24 channels and can be expanded in 24-channel increments, up to a maximum of 96 integrated channels, without requiring external boxes. The instrument features a built-in PC with a 10” monitor running Windows 10, allowing for intuitive management of settings, acquisition parameters, and data visualization. The system also includes a step-by-step guide for conducting common surveys.

Type of Instrument Stand Alone Seismograph

With its high flexibility and dynamic range, the X824S is ideal for a wide variety of seismic surveys, including surface seismic investigations like Refraction, Reflection (P and S waves), M.A.S.W., Re.Mi., E.S.A.C., borehole surveys such as Down Hole and Cross Hole, stand-alone passive station H.V.S.R., and vibrational monitoring. The 24-channel module supports a single cable with 24 takeouts, and the integrated battery pack minimizes the need for additional accessories on-site.
