The EG-1-HS-I is a 1Hz vertical high sensitivity seismic geophone tailored for microtremor observation. Adopting advanced moving-coil sensing principle, this ultra-low frequency transducer breaks the detection limit of conventional geophones and captures subtle ground motion signals for near-surface and deep geological research.
