P.A.S.I. seismograph Mod. 16S24-N is not only characterized by its innovative design

instrument, two powerful and sophysticated systems for a detailed environmental
www.pasigeophysics.com analysis) it really becomes the reliable solution for yours field applications.
Thanks to the large 10.6” LCD touch screen, the user interface results particularly
immediate and complete at the same time.
January 2007 The logical steps proposed for setting each kind of profile (refraction, reflection,
MASW, microtremors, downhole, etc..) by the sophisticated acquisition software will
Available Models allow the user to always take the situation under control.
All data are then saved on the internal hard disk, ready for a fast transfer to PC via
Mod.16S24-N (24 channels)
USB for the subsequent data processing.
Mod.16SG24-N (combined Finally, the integrated “DOWNHOLE” software module, which is fundamental for
system electrical imaging + facilitating this particular kind of acquisition (also refer also to DHTG borehole geo-
24 channel seismograph) phone description), is an important value added factor for the instrument.
