GEA24 is a compact-sized 24 channel seismograph (can be serialised for a total of 48 chan.) with a 24 bit data acquisition board and USB interface for external PC (not included in the standard supply). Suitable for all applications, GEA-24 is a reliable, affordable solution for all professional uses. Connected to your PC laptop or tablet, GEA24 becomes a seismic tool that is simple to use, but with top-level performance. An external 12V battery (heavy and bulky) no longer needed: GEA24 consumes very little and is powered directly from the PC, guaranteeing a long day of work on-site. GEA24 can acquire using geophones with any resonance frequency (even 1Hz). To get 48 simultaneous channels, just connect two GEA24s to the same PC, perhaps using the Radiotrigger accessory and using a land streamer or a hydrophone chain. Versatility is what makes this our best selling product.
