Short-period Seismograph

The GL-PS2+ seismograph is a miniature portable short-period seismograph developed for dense seismic observation. It integrates three-component seismometer, acquisition and storage circuit, dual TF card storage, data transmission and wireless WiFi into one unit. It supports Beidou timing and is equipped with an OLED display. It enables automatic pendulum unlocking after power-on and remote pendulum unlocking. It features compact structure and complete functions.

It is mainly applied to high-density seismic array observation, shale gas fracturing monitoring, ambient noise tomography, earthquake early warning monitoring, landslide and rockfall monitoring, and seismic safety evaluation.
