Transient Electromagnetic Instrument (Tunnel)
The GT-30 is mainly applied in urban engineering investigation, ultra-shallow investigation of urban road voids, pipelines, etc., and has strong anti-interference ability. As well as dam seepage, ant holes and cavities, etc.
Product Features:
-
Small in size, light in weight and convenient for construction. The receiver is a flat plate made of light metal material, which is lightweight and easy to carry, and features touch screen operation. Sturdy and waterproof.
-
The coplanar equivalent anti-flux transmitting and receiving integrated coil is easy and convenient to operate, and it also has the ability to detect large depths without blind spots.
-
High performance and low power consumption. The CPU is equipped with a 2.24ghz quad-core processor and a 32-bit AD conversion chip, featuring no operation delay, high measurement accuracy and wide dynamic range.
-
Our self-developed technology overcomes the "blind spot" problem inherent in transient electromagnetism, enabling effective ultra-shallow detection and precise measurement of shallow anomalies as shallow as one meter.
-
Advanced interpretation and processing software system. A full-space interpretation software system for underground work (such as underground tunnels, shafts, etc.), with user-friendly operation, one-click filtering and one-click mapping.
-
Universal transient electromagnetic receiver, which can be matched with different transmitters and coils, meets the requirements of transient electromagnetic detection in explosion-proof environments in underground coal mines, advanced prediction of tunnels and surface environments.
-
It can be interconnected with the online processing and interpretation system for advanced detection data to achieve real-time upload, storage, interpretation and mapping of geophysical exploration data.
