Y-7
AC/DC Electromagnetic Yoke

The Y-7 is a durable, high-strength AC/DC magnetic yoke designed to detect surface and sub-surface indications in the most rugged applications.

Featuring sealed chemical-resistant construction, articulating legs to contour to any part shape and robust strain-relieved twelve-foot cord for field use, the Y-7 is ideal for inspection of welds and other remote testing.

Solid-state controls allow the operator to use AC magnetic fields for surface indications or DC magnetic fields for sub-surface indications to meet all inspection needs.
​
The Y-7 is also available in the Y-7 MV Kit which comes with a Y-7 yoke, #1 Gray and #8A Red magnetic powders, a paint marker and hand cleaner towels in a convenient carrying case.
