Description
24 bit seismograph for seismic prospecting with refraction, reflection, active and passive MASW (Re.Mi.), SASW, Down-hole, Cross-hole, seismic tomography, HVSR investigation methodology. The unit is equipped with a capture card with 24 bit resolution. It is possible to serialize two units to reach 48 channels. Through the management software, to be installed on any PC or notebook connected to the acquisition unit, it is possible to set all the parameters relating to the type of seismic survey that you intend to carry out with maximum simplicity and speed.
