MARY Receiver (Multifunctional Electrical Prospecting Meter) is one of the newest and leading technologic innovation of portable geophysical equipment. It is compact and easy-to-use and allows end-users to perform different types of measurements such as structural, mapping, explorative, hydro-geological, engineering, archeological, geotechnical and ecological in short periods of time.
MARY is intended for:
Apparent resistivty measurements (amplitude of the first signal harmonic is measured);
Induced polarization measurements (phase-shifts between carrier-harmonics are measured);
Self potential measurements (constant component of the field if measured);
Frequency soundings
The device has a large LCD display, an ergonomic keyboard, and internal power supply, nevertheless it can use an external one.
During the process of measurement MARY registers input signal, processes it, shows the results on the display and records it to memory. In addition to this it allows recording source signals for further in-lab data processing.
