Product Description

EG-1-HS-II Ultra Low Frequency 0.75Hz Vertical Seismic Geophone for Long Period Microtremor Measurement

 

The EG-1-HS-II is an ultra low frequency 0.75Hz vertical seismic geophone optimized for long period microtremor measurement. As a high-performance moving-coil transducer, it breaks the detection limit of conventional low-frequency sensors and is specialized in capturing slow, long-cycle vertical ambient vibration signals for passive geophysical testing.
 
It adopts precisely matched magnetic circuit and coil assembly to deliver smooth frequency response within the ultra-low frequency band and suppress harmonic distortion effectively. It can pick up extremely faint long-period microtremor signals, supporting accurate H/V spectral ratio calculation and reliable evaluation of underground geological conditions.
 
Equipped with rugged sealed housing and built-in electromagnetic shielding design, this geophone can withstand shock, dust and various electromagnetic interference from the field environment. It maintains stable and repeatable signal output during long-term continuous unattended observation.
 
It is widely used for long period HVSR test, site effect assessment, soil stratification analysis, seismic hazard research and geoscience field experiments. Custom cable length and wiring configurations are available to meet different acquisition system requirements.
