Minimus - A revolution in miniature!

Minimus digitisers offer advanced 'smart' 24-bit seismic ADC conversion and are 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, 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 an ultra-low-latency mode which when used with our GDI protocol means network transmission can be achieved in 40 milli-seconds (network dependent).

Available in 4-channel (Minimus and Minimus2) or 8-channel versions (Minimus+).
The four channel Minimus can simultaneously accommodate a triaxial analogue sensor, an auxillary input e.g. for infrasound; a Radian posthole or borehole instrument; plus its own internal MEMS accelerometer (2g)
