G-822A Mobile Cesium Magnetometer:

The  G-822A is designed for all mobile and base station  applications where the unique  combination of high sensitivity and very rapid sampling and recording of the earth's  magnetic field are required. The system consists of a cesium sensor with its  associated  cables and driver electronic package, and a separate high resolution counter.

The G-822A operates on 24-32 VDC power and is compatible with all standard digital and  analog recording devices.

The  sensor uses a precise well-proven design to insure  high performance levels of sensitivity,  noise, heading error, and absolute accuracy. Tuning through the earth's field range is  fully automatic including the change of hemisphere. The  sensor/electronics package is  watertight, temperature controlled, and delivers full performance under extreme operating  conditions.
