iTem-prs series of infrasound sensors

The easiest and cheapest way to detect infrasound waves produced by different sources: volcanoes, avalanches, calving, ...

The iTem-prs series of infrasound sensors are designed for easy field deployment, low power consumption and robust weather sealed construction.

The iTem-prs series has low noise, stable operation, wide bandwidth and covers varying ranges of excess pressure.

The iTem-prs series have been used and tested in different hostile environments (Norway, Etna, Stromboli, Greenland) and for various applications, from explosive volcano and avalanches monitoring and alerting to gravity waves studies.

The versatility, reliability, robustness and medium / high sensitivity of item-prs together with the low price make it accessible for a wide spectrum of users.

  • Quick field deployment
  • Low power consumption: <300 mW
  • 0.01 Hz to 100 Hz bandwidth
  • 4-port manifold for wind-noise reduction array
  • Differential output
  • Very low noise floor
