ATEM-IV Transient Electromagnetic System

Main Features

1. the system can be used in investigation works including metal mine, coal field, oil field gas, geothermal, water resources survey and including environmental pollution detection,

2. By using the lead synchronization technology, ultra-high power detecting range can be extended from a few meters to a thousand meters;

3. by adopting IGBT bridge circuit, high-power, quick shut-off, portable electromagnetic transmitter can be realized;

4. by using floating-point amplification and FPGA technology, high-resolution receiver can be realized; USB port data transfer facilitates the man-machine dialogue,

etc.

5. with multiple function in one machine, with integration of superficial part and intermediate part, the instrument is suitable for the place with features like mountainous areas and complicated geological environment;
