The Model 475 DSP gaussmeter uses digital signal processing to measure DC and AC magnetic fields with Hall probes. Resolution is selectable at 5-3/4, 4-3/4 or 3-3/4 digits, trading reading rate against bandwidth. It is used for precise field measurement and magnet characterisation.

These Helmholtz coils generate a known, uniform magnetic field from an applied current, so they can be used to calibrate and check magnetic field sensors. Single-axis coils are offered in 2.5 in, 6 in and 12 in inside diameters, along with a 2-axis model. Field accuracy is 0.75%.
The Model 425 is a desktop gaussmeter that measures DC and AC magnetic fields using Lake Shore Hall probes. It reads at 4-3/4 digit resolution with the filter on, and covers ranges up to 350 kG depending on the probe fitted. It is used for magnet testing and field mapping.
These Helmholtz coils work with the Model 480 fluxmeter to measure the magnetic moment of permanent magnets and magnet assemblies. The sample sits at the centre of the coil pair and the flux change is integrated by the fluxmeter. Single and 2-axis configurations are available.
