Product Description

Digtal and Light Weight Seismograph





It is more widely used in research areas such as intensive earthquake networks and natural seismic observations, reservoir induced earthquake monitoring, mining earthquake monitoring and oil and gas exploration, and other broadband zone earthquake observations and underground formation. Wait for scientific investigations




1. Integrates a variety of functions such as integrated broadband seismic meters, collection, storage, data transmission, and detection

2. Inside contains 32 -bit collectors, small broadband zone seismic meters, data storage units, network communication, and GPS timing units

3. The signal conversion of vertical, east -west, and north after the coordinate is transformed.

4. The collector is used to collect the voltage signal of the output of the sensor, including three high -resolution, large dynamic range, and full balance differential channels of fast real -time data flow output, and has high time and time -conservative accuracy.
