Bartington MS3 / MS2B

The Bartington MS3 susceptibility meter is equipped with the classic MS2B dual-frequency sensor, which allows for the determination of frequency-dependent susceptibility at 470Hz and 4.7kHz. Contrary to the MS2 susceptibility meter, this model has no internal batteries and cannot be taken into the field without a laptop or similar computer. In my case, it pretty much lives in the lab.
