The SM-30 is a small magnetic susceptibility meter.  Thanks to the high sensitivity, it can measure sediments and rocks with extremely low level of magnetic susceptibility.

sm-30In addition, it can distinctly measure diamagnetic materials like limestone, quartz and also water. The SM-30 is controlled by three push buttons. One of them serves to save up to 250 measured values into non-volatile memory and to recall them later.  The SM-30 has a beeper indicating intervals in which the information from the rock is picked-up.

The SM-30 is powered from two coin sized lithium batteries (CR2430).  If the instruments are not used too extensively, the batteries may last for years thanks to their low self-discharge.
