These probes require a Gauss / Tesla meter to plug into (see Magnetometers). Compatible with magnetometers manufactured by F.W. Bell, Sypris, Pacific Scientific, OECO, Meggitt.
These probes use a Hall-effect sensor at tip of the probe stem to measure DC and AC magnetic fields.
"Axial" probes measure the magnetic field parallel to the probe stem.
"Transverse" probes measure the field perpendicularly across the probe flat surface.
"Standard" probes have a polypropylene stem and are recommended for laboratory or light-handling environments.
"Heavy Duty" probes have an aluminum stem and are recommended for heavy-handling environments.
