Güralp 3T Series Seismometers

The pioneer of miniature force-feedback seismometers

The Güralp 3T is the ultimate and original triaxial, broadband, weak-motion seismometer that provides exceptionally high quality monitoring over the long-period. Depending on the required level of performance and the location of the installation you can select from the following options:

3T-360 - an observatory grade instrument for monitoring over the very long period, in very quiet locations

3T-120 - for surface and sub-surface vaults, with the option for a polar casing which is operational and cold-start tested at -55 degrees Celcius.

3T-120 PH - a post-hole option suitable for permanent immersion in wet environments

We also manufacture a triaxial 3T borehole sensor which can be used alone or in combination with an accelerometer in a single instrument. For more information see our borehole and subsurface page.
