Digital Broadband Seismograph
- Traditional seismic prospecting and earthquake prediction systems in seismic stations;
- Quality inspection of civil engineering;
- Measurement of long-time ground micro-vibration;
- Monitoring explosion vibration.
Waterproof and anti-interference, digital broadband seismographs are suitable for geological fixed or mobile seismic stations.

- With a case made of high-quality alloy, the main unit is structurally firm, light weighted, waterproof and anti-interference.
- With internal BDS and GPS for locating and timing, the seismograph can be buried 0.2m~0.4m underground. External GPS with lightning arrester is optional.
- The internal Zigbee unit allows convenient wireless ad hoc network mode.
- Besides internal electronic compass and attitude sensor, the chargeable lithium battery allows continuous operation of over 30 days.
- The optional external 9～15V (0.5A～2A) DC power supply make the seismograph more suitable for long-time unmanned seismic observation in the wild.
