Güralp Radian

In 2016 we launched the Güralp Radian. The Radian is a slimline, subsurface, broadband digital seismometer that utilises state of the art technology in order to operate at any angle. This capability makes the Radian the ideal rapid deployment posthole instrument as it can be installed with a simple hand auger. A borehole Radian for vertical and non vertical cased holes is also available, and as well as individual deployments, it can be strung together to provide Vertical Seismic Profiling (VSP). For more information read the full Radian brochure here.

Güralp provide a range of instruments packaged for a number of different operating environments. We have a range of sensor families that vary in performance from very low frequency very low noise for global seismology to high dynamic range instruments for local strong motion monitoring.

Nearly all of our sensors are supplied for deployment at the surface, in boreholes and on the ocean bottom. We supply analogue instruments and separate digitisers, or integrated packages with a digital output.
