The SM-20 magnetic susceptibility meter serves a number of geological and geophysical applications where the unique sensitivity of 10^-6 Si units together with its small shirt-pocket size and light weight are appreciated.

The SM-20 is destinated especially for field geologists and for fast laboratory assays for analysis and classification of rock types. Measurements of outcrops, drill cores or other samples allow basic differentiation of rocks (diamagnetic, paramagnetic and ferromagnetic) and their precise susceptibility quantification.

The original sensor and a new method of signal processing (based on RISC microcontroller) guarantee advanced instrument features. The SM-20 is simply operated using two buttons (the first one for measurement and the second one for data storage). When used with PC control, via a RS-232 port, point labels, comments and data storage is available . Two Li cells supply power for 100 hours and the automatic power off function provide a long working time without battery change.
