Magnetic Susceptibility & Conductivity Meter are devices used to measure the magnetic susceptibility of geological samples or cores. These stand-alone meters feature a display and data storage capabilities. They are available in both circular and rectangular coil designs to measure large or small samples, respectively. These meters produce accurate results and offer three modes of operation (discrete measurements, continuous scanning, or borehole measurements). They also include split and full core corrections for standard drill rod diameters and non-standard sizes, the ability to input information to correlate measurements to their appropriate depths, a built-in microphone to record voice notes with measurements, and the GeoView data management/visualization software. Their compact and rugged design makes them ideal instruments for use in the field, core shacks, or laboratories.
