3D Geophones

This instrument is composed of three sensors ā€“ geophones with a fundamental frequency of 4.5 Hz or 10 Hzā€“ mounted at right-angles in a metallic container, and an equalizer for going beyond the frequency responses of a single geophone.
It is designed and built for measuring vibrations with frequencies between 2 and 250 Hz.
It can be supplied by an external power source of 220 VAC, at 50 Hz, or battery powered.
Two models of our G1-GEO 3DE are available ā€“ for wall or floor. Fastening to a support, achieved using four 8 mm-anchors, is ensured by four angled-brackets.
