Product Description

Digital 3C geophone EPS-2-M6Q portable micro-power seismograph

EPS-2-M6Q portable micro-power seismograph is a broadband , low-cost, micro-power seismograph. No need to lock the pendulum, no need to adjust the position of the pendulum, the transfer function is very stable, small size, easy to install and use, power consumption is less than 300mW digital seismograph. Built-in three-component seismic sensor, high-sensitivity Beidou+GPS module, electronic compass, attitude sensor, Bluetooth module and rechargeable lithium battery, it can work continuously for more than 20 days without any external power supply. It can realize timed start-up collection, and timed shutdown after collection; it can also be collected continuously; it adopts multiple interactive working methods such as USB, RS232, Bluetooth, etc.; data is automatically stored locally; it has the characteristics of Beidou+GPS timing and geographic location positioning. It is very suitable for unattended long-term timing detection, wideband seismic observation in the field, and natural micro-motion surface wave detection. Its high frequency reaches more than 200Hz, which can meet the needs of artificial seismic sounding and transient surface wave exploration.

The seismometer of EPS-2-M6Q portable micro-power broadband seismograph uses low-frequency moving coil transducer and electronic feedback technology. Its electronic circuit board includes electronic feedback circuit, acquisition control module, communication interaction module, DC power conversion module, etc.; The technical indicators are stable and superior.
