Multifrequency complex AEMP-14 is the final version of the three-coil induction system for electromagnetic profiling.

The principle implemented in the instrument allows to measure the distribution of apparent resistivity in the soil at a depth of up to 10 m. Equipment shows the best results in conductive media. Also good targets for it are more conductive objects (tunnels, underground shelters with wet walls, pipes, etc.) in less conductive soil.

AEMP-14 allows profiling on any set of 14 fixed frequencies in the range of 2 500 – 250 000 Hz, including with automatic referencing of the measurement point to global coordinates.

Ease of operation allows just one person to work with the instrument. AEMP-14 measurement results are visualized in real time on the Pocket PC screen, data and control signals are transmitted via Bluetooth. Upon completing the work, data is downloaded to a PC for further processing and visualization of the result in the form of maps or profile curves. Depending on the number of frequencies used, the survey speed can vary from 2 to 30 km/h (with a density of 2 m on the profile).
