Introduction:
The MT magnetotelluric instrument is deeply integrated with the operational habits of domestic exploration users, innovatively combining electrode connection testing functionality with an audio/low-frequency dual-mode observation system. Manual adjustment of the amplification switch significantly enhances efficiency in deep-depth exploration. The product is available in both standalone and web-based versions. The Web-MT magnetotelluric instrument supports real-time data upload to cloud platforms via 4G/5G networks, ensuring data security while enabling collaborative processing and analysis of exploration data.
Applications:
Resource Exploration:
Deep-mineral exploration, groundwater detection, fault zone identification, and void area investigation.
Disaster Monitoring:
Earthquake early warning and dynamic monitoring of geological hazards.

Features:
High-precision acquisition:
Built-in 4 or 5-channel synchronous 24-bit 102400Sample/s continuous sampling module, combined with a manual adjustable weak signal amplifier (maximum 8000 times gain), ensures data acquisition accuracy.
Anti-interference capability:
For industrial frequency 50Hz and harmonic interference, dual optimization technologies of physical shielding and data preprocessing are adopted.
Portability:
The high-frequency magnetic sensor independently developed weighs only 1.5kg. It abandons the traditional battery power supply and uses an internal lithium battery instead, upgrading the equipment's lightweight design.
Intelligent grounding detection:
Unique electrical channel connection testing function, intuitive electrode status judgment, enhancing the user's operation experience.
Robust impedance calculation:
Supports continuous data acquisition and real-time robust stacking operation, significantly improving the quality of impedance estimation data.
High efficient detection in MT test:
When using the common working frequency of 0.01Hz to 20kHz (the magnetic sensor's calibration frequency is 0.0002Hz to 50kHz), in the low-frequency detection mode, it only takes 17 minutes to complete the large-depth observation, with efficiency leading the industry.
