Product Description

Commodity name: Ant-1CE-5Hz

The Ant-1CE is an advanced nodal seismometer designed to streamline seismic exploration through reduced operational complexity, enhanced survey efficiency, and significant project cost savings

Single Component Seismometer with External Interface
Ultra Portable Nodal Seismometer: High Flexibility & Rugged Reliability
The Ant-1CE is an advanced nodal seismometer designed to streamline seismic exploration through reduced operational complexity, enhanced survey efficiency, and significant project cost savings. It integrates cutting edge GPS/Beidou synchronization algorithms, ultra low power circuitry, and wirelessdata/charging technology.
With high integration, extended operation time, and zero external contacts, it supports intelligent/automated deployment in complex terrains and harsh environments. The Ant-1CE's state of art ADC design delivers an exceptional dynamic range, exceeding that of comparable systems, allowing for the detection of micro vibrations.
Ant-1CE supports external connectivity with land geophone strings, marsh phones, and hydrophones.
UAV assisted surveys at altitudes above 300 meters AGL are supported.

Application Areas
Seismic zonation safety assessment
Shallow geological surveys
Urban subsurface space exploration
Geothermal exploration
Coal mine goaf detection
Exploration for petroleum, natural gas, coal
and nonferrous minerals, etc.
