24 Channels Seismograph for Seismic Exploration
The seismograph system is composed by two parts: the tablet PC and
the collecting unit. The data of collecing unit is transferred to
PC by USB port. Each parts is powered separtely, and the power of
the collecitng unit is available to switch freely.
Application:
1. Inspecting building base, roadbed and civil engineering
2. Engineering inspection
3. Large-scale and medium-scale water reservoir monitoring
4. Bridge engineering inspection
5. Environmental and geologic hazards detection and evaluation
Main functions:
1. Traditional shallow seismic exploration includes reflection and
refraction
2. Transient multi-point Rayleigh wave exploration
3. Multiwave high density seismic mapping
4. Civil engineering quality inspection
5. Long time field fretting survey
6. Blasting vibration monitoring
7. Shear wave velocity test
