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.

product
Very Broadband Borehole Systems
Borehole installations offer excellent performance for low-noise detection of weak seismic signals such as from local microseismic events or from regional/teleseismic earthquakes.
-
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.
