FEATURES
INSTRUMENT AND DATA
MANAGEMENT MADE SIMPLE
The ideal data acquisition partner for Hexis are our Minimus digitisers which provide state-of-the-art communication capabilities including versatile data streaming and storage capabilities and industry standard triggering algorithms.
By pairing with a Minimus you also access Güralp Discovery, our sophisticated instrument and data management software platform.
Discovery gives you access to hardware State-of-Health; data viewing; data streaming and back fill capabilities; advanced data analysis tools; GNSS location; instrument response and calibration values.
