The B-300MR 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-300MR 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.
The B300-MR contains electronic circuitry that is sealed within the instruments housing. The external push button switch magnetically activates the power circuit from the outside. There is no electrical contact between the switch and internal circuit. This instrument is ideally suited for high moisture areas.
