A revolutionary, compact seismic digitiser

Capture, Process, Distribute. A revolution in miniature.

The Güralp Minimus is a small, portable, 24-bit, four-channel digitiser, packed with a host of features that make it the ideal 'plug-and-play' solution for rapid deployments. For Earthquake Early Warning applications, the Minimus has a low-latency mode running causal filters alongside traditional acausal filters. When used with our GDI protocol this low-latency mode means network transmission can be achieved in 40 milli-seconds (network dependent). You can read more about our GDI protocol here.
