Portable Nodal Seismograph
Introduction
Portable Nodal Seismograph is widely used in various fields of oil and gas, coal resource and engineering 2D and 3D seismic exploration.
Features:
* The acquisition station uses 32-bit ultra-high precision Σ-Δ ADC with ultra-low noise level.
* Built-in GPS and high precision clock, can maintain long-term synchronization.
* Built-in geophone integrated design, small size, light weight.
* Use the charging cabinet for charging and data export simultaneously.
* Mobile APP can be used to carry out real-time quality monitoring at the acquisition site and record instrument operation and deployment information.
* Compatible with active source and natural source exploration methods.
* The exploration system supports more than 100,000 channels.
* Support SEG-2, SEG-Y, SEG-D, SAC, Mini-SEED and other data formats.
* Equipped with 32 channel charging and data recovery cabinet, charging and data export at the same time.
