1 Maximum field depends on pole gap; measuring large samples may decrease maximum field.
2 Low-temperature VSM converts to AGFM. Only one may be used at a time.
3 While the AGFM can be used at low temperature, any benefits over the VSM in signal-to-noise ratio become smaller with decreasing temperature.
4 This magnetometer system has in-line ARM and and off-line IRM capabilities.
