Plug-In Magnetic Particle Flaw Detection Kits

Find faulty seams, welding defects, and other surface-level flaws in ferrous materials. These kits come with everything you need to start inspecting parts. Apply the powder to the surface you want to inspect. Then plug in the yoke and it creates a magnetic field that draws the powder to the imperfection, making it easy to spot. Built for rugged environments, the yoke has a sealed design that stands up to chemicals and other harsh conditions. It’s also half the weight of a standard yoke and fits comfortably in your hand, so there’s less fatigue if you use it for extended periods of time.

Battery-Powered Magnetic Particle Flaw Detection Kits

Check for defects slightly beneath the surface of ferrous materials that you wouldn’t otherwise see. The yoke in these kits is powered by a battery, so it uses direct current to create a strong magnetic field that reaches just below the surface of your part. When you apply the powder, the powder will move towards any flaws, helping you identify tears, cracks, and other imperfections.

Ideal for fieldwork, these kits come with everything you need for on-the-go inspections. The yoke lasts up to eight hours on a single battery charge. Built for rugged environments, it has a sealed design that stands up to chemicals and other harsh conditions.

Plug-In Magnetic Yokes

Find welding defects and other flaws in magnetic materials. These yokes create a magnetic field that draws magnetic powder (not included) to imperfections, making them easy to spot. All operate on AC power, which creates a small magnetic field ideal for detecting flaws along the surface of materials. Powered by standard electrical outlets, these yokes have a reliable and consistent power source.

Attach an LED light to your yoke to brightly illuminate inspection areas. They’re powered by the yoke’s magnetic field, so they don’t require batteries.

Calibrate your yoke before each use with a test weight to ensure accurate test results.

AC/DC Switch—Yokes with an AC/DC switch can also operate on DC power. DC power generates a deeper magnetic field than AC power to find defects underneath surfaces, such as internal tears and cracks.

6 lb.—6-lb. yokes are lightweight and fit comfortably in your hand to reduce fatigue over extended use.
