HX-DZ-04A series multi-channel distributed seismograph adopts distributed network design, with high integration, small size and lightness The stations are cascaded by TCP IP network protocol, which can be extended to 2048 channels
1. Compact size, low power consumption, strong anti-interference capability and less noise (background noise can be monitored in real time)
2. can be telecontrolled based on TCP/IP protocol via connecting laptop computer
3. Expandable channel: It can be expanded to maximum 2048 channels when stations are cascaded by TCP/IP network protocol.
4. Enables large dynamic rang, high fidelity, high sampling rate and minimum sampling interval of 5μs.
5. Stable performance and perfect for harsh environments: the excellent internal assembly process and the use of imported engineering case make it damp-proof, shockproof and dustproof.
6. Multiple built-in self-testing functions, including geophone testing and channel testing.
7. Background noise can be monitored in real time to provide a better environment for data acquisition.
8. Multi-function and multi-purpose: Not only can it be used for refraction, reflection, seismic CT and other data acquisition but also for continuous monitoring and acquisition.
