Triaxial Broadband Seismic Recorder Wide Band Seismograph Node Seismograph Digital Nodal Seismograph Geophysical Equipment
GD-3C broadband seismograph is a kind of broadband, low price, and micro-power seismometer. It is a small volume digital seismometer with the power consumption of less than 150mW that can be conveniently installed and used.
New generation 3C seismic node with ultra-high resolution, has integrated GPS/BDS clock synchronization algorithm, ultra-low power design method, most advanced wireless charging and wireless pulse communication technologies. It is highly integrated, no connectors with long battery life, and high reliability which is potential to be used in any harsh environments. The new analog-digital conversion technology is used to greatly improve the dynamic range rather than other equipment, it means detect weaker vibration signal.
