Seismometers
3ESPC Series
-
The Güralp 3ESPC is a proven weak-motion triaxial broadband seismometer for the price and size of a medium-motion instrument.Ideally suited for long-term temporary and permanent installations in areas with low to moderate noise levels. The instruments' broadband response and low self-noise level make it suitable for seismic monitoring at all scales: local, regional and teleseismic.

Product
Fortis and Fortimus
-
The Fortis and Fortimus are strong motion accelerometers, making them ideal for local earthquake early warning and structural health monitoring applications. They all feature flexible gain options so they can perform optimally in a wide range of earthquake monitoring scenarios.

Product
Certis and Certimus
-
Both instruments have a wide frequency response of 120 s - 100 Hz and benefit from a remotely adjustable long-period corner between 1 and 120 seconds.

Product
Downhole Minimus
-
For deployments exceeding 100 metres in depth, we recommend the Downhole Minimus digitiser. Digitizing the data at source ensures that the origin can be definitively traced and not subject to attenuation during the travel to the surface; so signals are stronger and more reliable.
