The MS3 Magnetic Susceptibility Meter is a new instrument, offering a wider measurement range (up to 26 SI) than the MS2 Meter. Additional features include a selectable measurement period and a USB or RS232 interface. It’s an ideal instrument for soil, rock, powder and liquid samples in geoscience, iron and copper ore process monitoring, and many other industrial applications.

This product consists of a small electronics module and new Windows-based software “BartSoft”. All user-control and display functions are provided within BartSoft, which can be run on a desktop/laptop PC for laboratory use or a handheld Windows Mobile device for field use.

The MS3 Meter is now recommended for laboratory-based users, in preference to the MS2 Meter. It is currently available with software for Windows desktop (2000, XP, Vista), and is suitable for use with the MS2 laboratory sensors MS2B, MS2C, MS2E, MS2G, and MS2K (indoor use).

Users of field probes (MS2D, MS2F, MS2H, MS2K) will require software for Windows Mobile Devices, which will be ready in early 2010. A full solution of the software with a logging GPS device will also be available then.

The MS3 Meter, with MS2 probes, is the ideal instrument for soil, rock, powder and liquid measurements in environmental science, geophysics  and industrial applications. The increase in the upper range, compared to its predecessor the MS2, permit its use in iron and copper ore processing, and other situations where samples with very high magnetic susceptibility are encountered.
