Product Description

CSAMT Method Deep Ground Geophysical Survey Equipment

By using a fixed grounded dipole or horizontal loop as an artificial signal source, the CSAMT method is is used to detect underground structures shallower than 2 km. Compared with traditional multi-electrodes resistivity or IP method, it has the advantage of more simple operation, deeper exploration depth, longer mesuring period. It is the ideal instrument for mineral, geothermal and ground water exploration.

Features & Function
