Parker Research was the originator of the flexible-leg magnetic inspection yoke (trade named Contour Probe) and has been manufacturing portable Magnetic Particle Inspection Equipment and accessories for over forty years.
Parker Research offers a great selection of Yokes, Coils, and Portable testers.
Made in the USA
When purchasing a yoke for magnetic particle inspection, we know that there are many factors to consider. That’s why we’ve provided you with the following guide. We’ve taken each of the most common purchasing considerations and matched them with the Parker yoke (or yokes) that we think suits it best. Of course, we encourage you to browse the subsections below, or call us for more details.
Safety
If the yoke is to be used for Wet Method MPI, or if the user will be standing on a wet surface or with wet hands, he/she should consider purchasing the B-300MR or B-300UF, as they provide the highest degree of electrical safety.
Price
All Parker Research’s yokes are considerably less expensive than other main brands and they are available in more models. The B-100 is the least expensive.
Weight
If the yoke will be held for a considerable length of time, its weight needs to be considered. This is especially important when working vertical and overhead. The P-2 is the lightest at 4.6 pounds.
Physical Size
For inspectors with small hands, the P-2 or B-200 should be considered. They have the smallest grip, at 1 5/8” x 2 1/8”.
On/Off Switch Placement
Top-mounted on/off switches are operated with your thumb, while handle-mounted switches are operated with your forefinger. We have heard that yokes with forefinger control are less tiring when used for a long period of time. UW-12 with handle-mounted switch shown above.
Field Strength / Pulling Power
The B-310 was developed to be used wherever there is limited access. The power cord can be positioned vertically if needed.
CE Certifications
CE certification is required for all yoke sales to European countries and is only available for 230V models.
