Proton Gradiometer PMG-2 is a portable instrument intended for ground measurement of the absolute value of the magnetic induction vector of the Earth's magnetic field by measuring the frequency of the precession of hydrogen nuclei protons. Data recording is fully automated. In survey applications actual position coordinates are recorded either by automated incrementation or by operator entry commands. The gradiometer can powered from external power source, namely in the base station mode.

The PMG-2 allows measuring in three modes:

SINGLE MODE is used in a profile magnetic survey with one sensor. It detects the absolute value of the magnetic field in the location of the sensor.

GRAD MODE - in this mode two sensors are used. The magnetic induction vector in the locations of both sensors are measured simultaneously. The horizontal or vertical gradient of the magnetic field between two sensors is determined by subtraction.

AUTO MODE - allows repeated measurement with one sensor in set time intervals. Both the starting time and the time interval can be set prior to the measurement. This mode is used for measuring diurnal variations of the Earth's magnetic field.

The results of the measurements can be stored in an internal protected memory. The recorded data are not lost when instrument is switched off or when the battery is removed. The data can be transferred to the computer using supplied communication software.
