High performance, low noise, compact, broadband accelerometers

For strong motion we recommend the analogue Güralp Fortis triaxial accelerometer which is available as a surface or a posthole instrument and the digital Güralp Fortimus which combines the Fortis with the feature-rich Minimus digitiser. However, if a single axis or borehole accelerometer is required, we can supply the a 5U accelerometer or a 5 series accelerometer in a borehole casing. The 5 series is a triaxial, force-feedback instrument with a large dynamic range .

Key Features

  • Force feedback broadband instrument
  • Waterproof and durable with O-ring seals throughout
