A revolutionary, compact seismic digitiser, now available with eight primary digitisation channels

Capture, Process, Distribute. A revolution in miniature.

Introducing Minimus+, all the power and capability of Minimus but with eight primary digitisation channels.

The Güralp Minimus (four channel) and Minimus+ (eight channel) are advanced 'smart' 24-bit seismic digitisers, packed with a host of features that make them the ideal 'plug-and-play' solution for rapid deployments and multi-scale networked arrays. For Earthquake Early Warning applications, their features include industry standard triggering algorithms (STA/LTA); multi-instrument voting to mitigate false positive alerts; Common Alert Protocol (CAP) for automated emergency warning; plus they can run in ultra-low-latency mode which when used with our GDI protocol means network transmission can be achieved in 40 milli-seconds (network dependent). You can read more about our GDI protocol here.
