Product Technical Advantages
1. Analog to Digital Converter (ADC) 32-bit and Low Noise Circuit Design Techniques At present, the products of major domestic and foreign manufacturers are all 24 bit ADCs. The 32-bit ADC used in GS201-C has higher conversion accuracy, lower noise, and higher dynamic range.
2. Multi stage configuration of preamplifier
Front amplifier gain range: 0dB, 6 dB, 12 dB, 18 dB, 24 dB, 30 dB, 36 dB.
Compared to other instruments at home and abroad, it has more gear options and is more convenient for collecting seismic waves from different geological regions
3. Powerful instrument Self inspection function
The instrument can achieve online self inspection of various parameters, and real-time online monitoring of the internal status of the instrument shell (voltage, temperature).
Self inspection and monitoring can be displayed in real-time on the main control laptop software interface.
4. The overall performance of the instrument reaches or exceeds the international advanced level
The GC201has undergone multiple comparative experiments and tests in the laboratory and field with instruments sold in China by France and the United States, and its main indicators are superior to foreign instruments.
5. The instrument is stable and reliable
All industrial grade chips, military grade connectors
The buffering structure of the instrument has been patented and tested through waterproof, dustproof, and impact resistance tests.
6.Professional customization
According to the special needs of users' exploration operations, "private customization" can be carried out to adjust parameters and software functions to better meet the professional requirements of users.
Conclusion: The seismic channel with the highest resolution data today.
Structural optimization, capable of collecting the most accurate data in the shortest possible time and requiring very few operators
