The Titan Accelerometer is also offered as a Posthole, that is ideally suited for national networks and research applications requiring reliable and durable instrumentation for strong motion and free field studies. The accelerometer is housed in a waterproof stainless steel enclosure and can be deployed in a direct burial posthole or cased borehole, which enables co-location with broadband posthole seismometers.

The Titan Posthole features industry leading dynamic range that, when combined with ultra-low self-noise performance, mitigates cultural noise resulting in precise measurements and high quality data.


  • Industry leading 166 dB dynamic range
  • Ultra-low self-noise comparable to some broadband seismometers
  • Wide operational frequency range: DC to 430 Hz
  • Best in class thermal stability and high accuracy provide increased data quality
  • Full scale range of ±0.25 g to ±4 g with independent horizontal and vertical range selection
  • Electronically selectable full scale range facilitates remote sensor control when deployments are distant or dif?cult to access
  • Integrated web server provides efficient instrument management and control
It is not about ideas. It is about making ideas happen.
