GE-ANT-1C Seismic nodal instrument
Abstract
GE-ANT-1C is a lightweight, convenient and stable seismic nodal instrument. Aiming simpli-fy seismic exploration, improving construction efficiency and saving project cost. The prod-uct adopts advanced GPS / BDS synchronization algorithm, ultra-low power circuit design and wireless data download / charging technology. High product integration, long continu-ous working time, IP68 waterproof, great potential for intelligent / automatic construction, and adapt to various complex surfaces and rugged environments.
Applications
● Seismic regional safety evaluation
● Shallow geological survey
● Urban underground space exploration
● Geothermal exploration
● Coal goaf exploration
● Mineral/ natural gas exploration
