Upgrade Choice for Global Seismic Networks

The Quanterra Q330HR sets a new performance standard in seismological instrumentation, building upon the widely praised ultra-low-power Q330. The Q330HR breaks the 24-bit performance barrier to extend the capability of advanced instrumentation for research. The Q330HR remains 100% compatible with our Q330. See Q330HR data sheet for a general and functional product description.

Same Exceptional Features as Q330

Multiple Network Access for:

  • Telemetry and Local Recording
  • Internet-Ready Industry Standards
  • Comprehensive Sensor Control
  • Streamlined Remote Administration

High! Resolution

The Q330HR sets a new standard, requiring 26-bit resolution to fully represent its dynamic range. The ‘HR exceeds GSN-class standard set by Quanterra nearly 20 years ago.
