F.W. Bell Probes

These probes plug into an F.W. Bell Gauss/Tesla meter  manufactured by Meggitt, OECO, Sypris, or Pacific Scientific.  

These probes use a Hall-effect sensor located near tip of the probe to measure DC and AC magnetic fields. 

These probes are single-axis (Axial or Transverse) probes. The field orientation is shown by a “+B” arrow on the probe datasheet

    "Axial" probes measure the magnetic field parallel to the probe stem.

    "Transverse" probes measure the field perpendicularly across the probe flat surface.
