New seismometer and digitiser launched at AGU Fall Meeting

Güralp, the leading global provider of force-feedback seismic monitoring instrumentation is launching Certis alongside a new low-power digitiser, Minimus2, at the American Geophysical Union Fall Meeting this week in Chicago, USA.


Certis offers maximum flexibility for installations in challenging conditions. The state-of-the-art digital sensor can operate at a tilt range of ±90° and has a wide frequency response of 120 s to 100 Hz making it suitable for local, regional and global seismic monitoring.

In addition to a configurable long-period corner, which allows the response of the instrument to be adjusted to suit the deployment environment, the Certis also delivers digital and/or analogue outputs with state-of-health parameters for confident long term monitoring applications. Certis is encased in an environmentally sealed stainless steel casing measuring 80 mm wide by just 112 mm high and is suitable for direct burial or posthole deployments to 10 m.

Güralp Systems (www.guralp.com) is a leading global provider of sophisticated seismic monitoring solutions used to understand natural seismological events such as earthquakes, aftershocks and volcanos, as well as induced seismic events, or seismic signals, resulting from human activity.

Our solutions are used in research, civil and industrial applications to increase understanding, optimise processes and to protect people and the environment. Our equipment is installed in all major ocean basins and across all continents worldwide.

Our instruments range in performance from very low frequency, very low noise for global seismology to high dynamic range instruments for local, strong motion monitoring. Our sensors and can be supplied for deployment at the surface, in boreholes and on the ocean bottom. We also provide data acquisition equipment, power and communication accessories and data interpretation software.

Our services include installation and commissioning; network operation; repair and maintenance services; data processing and interpretation.

Headquartered in Reading, in the UK, we have been operating for more than 30 years and have established a global network of distributors who provide local customer support and sales services.
