Stratavisor

Suitable for seismic reflection, refraction, downhole, crosshole, tomography, surface wave, or marine surveys, and seismic monitoring. System is housed in portable, ruggedized case with built-in, daylight-visible 800x600 color LCD and thermal graphics printer.

Operates under Windows XP multi-tasking OS and runs on Pentium-class processor.

High-speed over-sampling combined with digital signal processing provide a 24-bit result using Crystal Semiconductor sigma-delta A/D converters.

PASSCAL has been upgrading its pool of Multi-Channel Dataloggers in recent years to include multiple ES-3000 Geodes and a 60 Channel Strata View NZXP. These upgrades are also compatible with all of PASSCAL's Multi-Channel Cable System, which were originally purchased for use with the Geometrics StrataVisor NX. These  Units employ a new concept in portable exploration seismographs. They combine the ruggedness and high signal quality of a distributed system with the convenience and cost effectiveness of personal computer-based control devices. See Geode and Stratavisor Dataloggers for more Details.
