Single/Three-Component Node Seismograph

GL-JD1/3 Single/Three-component Seismograph is a wireless nodal seismograph integrating seismic sensors, high-performance collector, GNSS time server and lithium battery. It supports wireless and wired charging and data transmission. The wireless mode facilitates field equipment arrangement and data recovery, and the wired mode provides more expansion interfaces for long battery life and deep buried timing applications.

It is mainly used for coal mine and metal mine detection, shallow geological survey, coalfield goaf exploration, geothermal resource exploration, debris flow and landslide disaster early warning detection, and urban underground space detection.
