Main Applications and Features

Adopt lead synchronization technology, the detecting range can be within a few meters to a hundred meters. By adopting IGBT bridge circuit, high-power, quick shut-off, portable electromagnetic transmitter can be realized; by adopting floating-point amplification and FPGA technology, high-resolution receiver can be realized; USB port data transfer facilitates the man-machine dialogue, thus providing a complicated-geological-environment-fit, portable electromagnetic system for geophysical prospecting and engineering exploration; the system can be widely used in various aspects including geophysical prospecting, engineering detection, water resources survey and environmental pollution detection, etc.
