Features & Benefits
This handheld instrument is capable of measuring the magnetic susceptibility, conductivity, chargeability, resistivity and density of a sample. Its modular design provides the user with the ability to employ different sensors of optimal frequencies for either magnetic susceptibility or conductivity measurements. Additionally, density measurements are available as an option, providing more information about the sample. A picture, audio note, text note and GPS coordinates can be added to the measurements to increase the amount of information one can attach to each record.
