Employing the latest in seismograph technology, the OZA IV¨ incorporates dual mode operation - simultaneous peak interval and full waveform recording. Upgrades include a frequency analysis calibrated to new ISEE performance standards. Consider the portable printer option available for quick field reports. The OZA IV¨'s frequency response exceeds ISEE published performance standards.

A new large LCD display allows for easy field viewing. Included is an ultra high performance microphone. The new OZA IV¨ also employs a proprietary data compression scheme optimized for seismic data. The unit is both water and dust tight and has a rugged design to withstand the elements of a typical work site. Unit can continuously monitor for up to 110 hours before recharging.

Military grade interface connector means no fragile cabling. Memory upgrades allow for up to 250 events to be recorded and stored.

DOWNLOAD / ANALYSIS SOFTWARE Software designed to function smoothly in a Microsoft¨ Windows¨ environment. The OZA IV¨ software ensures that report generation, data storage to disk, generating ASCII files and communicating with the seismograph is user friendly. Generated reports include standard time history and Fast Fourier Transform or Dominant half-cycle peaks and frequency analysis. View or print the displacement, acceleration, velocity time history, or peak level bar graph. Intuitive, network ready file management database. Selectable views including variable zoom options, full screen frequency analysis, pinpoint sliding cursor, multiple event viewing and user selectable frequency limits. Vibration specifications can be added without software upgrade.
