6.1. General Description
The MS2B dual frequency sensor is a laboratory sensor designed to measure samples in
containers that are placed into the sample cavity.
The sample containers accommodated by this sensor are those commonly in use in most
palaeomagnetic and mineral magnetic laboratories; thus measurements of NRM (natural
remanent magnetisation), IRM (induced remanent magnetisation), ARM (anhysteric remanent
magnetisation) etc. can be carried out without any further sample treatment.
The sensor characteristics are optimised to produce no measurable response to sample
conductivity in, for example, even 25% saline solution. Even metallic conducting material can
be measured provided it is divided into a granular form to reduce the apparent diamagnetic
contribution that might otherwise result due to eddy currents.
