All available Hall probes are either compatible with the new generation of gaussmeters, systems F41 and F71, or the old generation of teslameters, models 475 and 425. Hall probes of the FP series are compatible with the F41 and F71 Hall measurement systems while Hall probes of the 400 series are compatible with teslameter models 475 and 425. See below a table of the stocked probes and their major specifications.

The probes can be differentiated by their detecting geometry, which is either axial, transversal or 3-axis (FP series only).
Transverse probes, most often rectangular in shape, measure fields normal to their stem width. They are useful for most general-purpose field measurements and are essential for working in magnet gaps. We offer several stem lengths and thicknesses as standard probes.
Axial probes, usually round, measure fields normal to their end. They can also be used for general-purpose measurements but are mostly used to measure fields produced by solenoids. We offer several stem lengths and diameters as standard probes.
The design of 3-axis probes is like that of the transverse probes. However, they deliver full vector field measurements in all three axes.
Aluminum as stem material is the best choice for DC and low-frequency AC measurements. Non-ferrous metals are used for probe stems, because they provide the best protection for the delicate Hall effect sensor without altering the measured field. However, metal stems have one drawback: they create eddy currents when placed in AC fields. These eddy currents oppose the field and cause measurement errors. Non-metallic fiberglass stems are used for higher frequency AC fields and for measuring pulse fields. Though this means less protection for the sensor, eddy currents are avoided so the frequency range of these probes is not limited.
