Parker B300 Contour Probe

The B-300 Contour Probe is a lightweight (7½ pounds) Magnetic Inspection Yoke designed to perform magnetic particle inspections quickly and reliably.

As with the other Parker probes, the B-300 has fully adjustable legs which allow the strong AC field to be applied directly to the precise area to be inspected, regardless of part size or mass.
