EPS portable digital seismometer is a stand-alone and broadband seismometer. It is no need to lock the pendulum or adjust pendulum position, and the transfer function is very stable. EPS digital seismometer is embedded with three-component geophone sensors, high-sensitivity Beidou +GPS module, electronic compass, attitude sensor, bluetooth module and rechargeable lithium battery, which enable the seismometer could continuously work for over 20 days without any external power supply. EPS digital seismometer owns the functions of timed power-on acquisition, timed power-off after acquisition, or continuous data acquisition. It adopts USB, RS232, Bluetooth and other interactive work mode and data will be automatically stored locally.

EPS portable digital seismometer owns the features of Beidou +GPS timing, geographical location positioning, independently long time working, low-power consumption and etc. It is very suitable for unattended long period timing observation, natural micro seismic surface wave exploration and broadband seismic observation in different fields. The frequency response range for EPS portable seismometer could be more than 200Hz, which affords the requirements of artificial seismic sounding and transient surface wave exploration.

Main Functions:

• Traditional seismic exploration and seismic station prediction system.
