The Güralp 3T is a triaxial, broadband, weak motion instrument, suitable for surface vault, subsurface vault and post-hole installations. The 3T is widely used on many National Seismic Networks, with in excess of 3000 triaxial sensors deployed worldwide.

The sensor includes motorised locking mechanisms to protect the sensitive components during transport, and the Gecko seismograph include controls to lock, unlock and centre these components without the need for a separate breakout box.

The sensor is available in a number of analogue and digital output packages, as well as a borehole package.
